What's your estimate then? I mean... I'm here in Portland. I can drive right by downtown (drove straight through Ground Zero at main and 3rd just this morning). I see the hippies. I don't see violence. Show me the violence. Tell me why I need to support tear gassing these kids every night for two months. No one will. But I see people vote up these posts about "yay lasers!" instead. I'm out of patience here. I can see…

Well, "no violence that I have personally seen during the day" doesn't really have any relevance to "is there violence during the night" - and all the police brutality / protester violence / arson etc videos I've seen from Portland have been at night.

I can't speak for Portland, but I have seen the SPD instigate violence on numerous occasions, against peaceful protests. In those instances, including in the time leading up to the violence - nobody was throwing anything at the police lines, nobody was destroying property - until the police started chucking flash and gas grenades and firing less-lethal bullets into crowds. (Which have all, by the way, been outlawed by city council - yet the police department is still using them.)

That is not how every Seattle protest has gone, but that's how many of them have - many during the day (Although a few turned that way at night, as well).

From friends on the ground in Portland I will say it's largely still aggravated by police presence and the DHS/federal agents. If authorities did not step in with tear gas and kidnapping protests would have continue to be mostly nonviolent. Turns out that when you meet protests against police brutality with police brutality and disappearing citizens, nothing improves. There are small groups and agitators causing issu…

What other protests have anywhere near this much violence? Gay rights movements have had large protests/marches for decades. Same with anti-abortion activists (and pro-choice activists). Hell, even literal neo-nazis have protests that don't get this violent.

This is a protest against the police. So of course the cops are going to get violent. What's horrifying is the extent to which people refuse to see that and just figure "well, the protesters have to have done something to deserve it".

What would a retroreflector on the target do to the dazzler's operator?

I assume that the scope has a 532 nm bandstop filter to prevent that issue. Also, the eyesafe feature probably triggers on retroreflection from a target's eyes, so a retroreflector would likely trigger the laser to reduce it's beam power.

One photo had a Trijicon RMR red dot optic. Doubtful it has 532nm protection. Mine doesn't.

So then the adversaries could wear laser safety glasses with the same 532 nm bandstop filter? Seems like a simple fix for them.

I don't necessarily get the sense this is made for "adversaries". More for unknowns. E.g. if voice commands and the laser fail (say, because it is a real adversary wearing safety glasses), next up is lots and lots of bullets.

Looks like a slightly modified Ruger 10-22 folding stock with some optics & a laser mounted. https://www.midwayusa.com/product/1006745523

Makes sense. The 10/22 is indestructible and proven. I've had one since I was 10 and put at least 20000 rounds through it and cleaned it once. It almost never jams.

Ok so destin works as a scientist for the us gov. He did a video a while ago where he interviewed a general about the cyber domain of warfare. In this interview they discussed that the interview itself was part of that cyber domain, and the access they provide to destin is a part of the US presence in the cyber domain.

marketing is not propaganda.

Marketing for the military capacity of a state is pretty much the definition of propaganda :)

So the clarification (easily determined from the subtitle, as well as the article body), is that this is a dazzler meant to temporarily blind or distract. It's not a sci fi laser rifle that cuts things. This is very different from star wars (the missile defense program), or star wars (the movie). The US Navy does have things closer to that: https://www.popularmechanics.com/military/navy-ships/a326766... But they're h…

It sounds like it is more of a warning "you are in our way" device? "For long-distance hail and warning, especially during maritime security, the GLARE® LA-9/P combines a powerful green beam with Eye Safe® technology. The laser rapidly determines if an unintended observer is within the nominal ocular hazard distance (NOHD) and immediately shuts off the glaring output to prevent accidental eye injury. Once the bystand…

How does it do that? I mean, I know of no technology that could do what this tech claims to be able to do.

EDIT: my guess is that it's actually unable of distinguishing the target and WILL blind you but the quip about being non-blinding is because of the Geneva convention, since, apparently, blinding weapons are illegal.

The youtube channel smarter every day is doing a series about live aboard a nuclear attack sub (different class than the one in the article, Los Angeles class IIRC) during an exercise where they navigate under ice, called ICEX. which might be of interest if you like this article. It's obviously propaganda but it is very interesting nonetheless. actual submarine part: https://youtu.be/RXXMJAU6vY8 the leadup and contex…

>It's obviously propaganda but it is very interesting nonetheless. Sorry, how is this video obviously propaganda?

I am assuming the idea that approval/invitation of a video from the subject is by definition propaganda of the subject. Just like sponsored product reviews or manufacturing tours. If you understand that he will not say much of anything negative then it is fine.

Two side observations unrelated to the laser rifle: 1) It's surprising or kind of amusing that such a huge and complex submarine uses plain old Raytheon / Raymarine radar when operating in harbor, etc. as if were just a little sailboat. But whatever works and is effective! I wonder how it has to be dismantled and put up, taken down each time? Perhaps it's mostly for being visible to other ships/monitoring stations? I…

Stealth ships and aircraft won't turn on the fancy toys when they are in predictable locations to avoid adversaries being able to collect and analyze signals intelligence.

Not a protest per se, but riots did result from police violence against the gay community.
