Earlier quoted context omitted.
Sadly, a video of a random figure with face obscured throwing a rock through your car window isn't going to get the police involved. Even with a GPS location of someone you pranked with a package, if there's no evidence directly tying the two incidents, the police aren't going to waste resources doing CSI on it. They'll just write you a police report so you can get your insurance paid.
Disturbingly, the accidental message of this glitterbomb booby-trap video is that you will probably not face legal consequences for stealing packages from peoples' property in broad daylight, so even the best security cameras are effectively useless.
The police are a business and if there's not money to be had (traffic citations, parking tickets, etc.), or violent crime happening, you are the lowest possible priority. Source: personal experience + have worked with a couple of police depts many years back (not as a LEO). The only exception here is if you're a reasonable sized business - they tend to take cases like retail/corporate break-in seriously.
TLDR: Agree. People wouldn't do this if there were a real legal cost.
