Camera mounted on AR-15 lower
I have blogged before about cameras being mounted on rifle stocks. SayUncle found this webpage showing a camera mounted on an AR-15 lower.
This is an incredibly bad idea. Not only could people could easily it for a gun-like weapon, but an AR-15 lower is legally a firearm. I doubt the cops would be very happy about it being waved around in a public space.

I’m all for using common sense in public, for the common good, but what cops think quit mattering to me long ago.
But does it take a picture when you pull the trigger is the real question.
And if you switch to full auto…does it take continuos photos, or only 3 “shot” bursts?
Interesting legal issues if someone were to get arrested for this and then refer to the second amendment…
But I agree you should always try to avoid looking like you are pointing guns at people, regardless of laws (unless you actually are pointing a gun at someone, of course…).
The gallery for your pic includes a “what if ” scenario.

Caption, “… Now pretend you’re a cop. Shoot or don’t shoot?”
I’d bet there’s some tongue-in-cheek going on there.
I saw an article a few months back about a military photographer who had a similar device that’s just as nonsensical, but at least doesn’t require an actual lower receiver. It still seems like stupid and counerproductive behavior.
