"the FBI said they are not seeking to set a precedent in the case, but to get the company to help them open a single phone that may hold crucial evidence to help explain the most deadly terrorist attack on U.S. soil since Sept. 11, 2001." What qualifies this as being a terrorist attack? Is it because the colour of the perpetrator's skin wasn't white? Sandy Hook had double the number of resulting deaths and so is tech…
A terrorist is someone who uses violence or the threat of violence to coerce or intimidate. Revenge murders or anger murders are not terrorists. They kill people and then kill themselves; directly or by police. Because they are dead they are no longer a threat. There is no parent organization to fear. At least that's my definition. And what I think along the lines of what most people intuitively think.
To me, terrorism is the use of stealth to deliberately target civilians in a media effort to change political opinion.
I've had this definition for several years, and I have never reached some of the crazy conclusions other commentators reach about the topic "George Washington was a terrorist!" "One man's terrorist is another man's freedom fighter" and so on.
Definitions matter.
Note: This is not related to the merits of the FBI's case. My point is simply that we can all use the word "terrorism" and all actually be talking about different things.
