Oh yeah, I've seen plenty of those little weed one hitters. Looks exactly like my KR808d-1 I have sitting in my kitchen. I see nothing wrong with what happened and if you have nothing to hide, what's the big deal. It's not like he was assaulted. Big whoop. So he had his hands on his head. Boy, that must have scarred him for life. Sure, there are some police who are shady, but if you're doing nothing wrong, most of the time they are very reasonable people. And oh yeah, this might come as a shocker to a few of you but they are not robots. They are HUMAN! So unless you have never made a mistake before in your life, don't be so quick to judge someone else cuz in the words of Bob Marley, "Judge not", "Cuz someone else is judging you".
Seriously, anyone saying otherwise is a hippie.
Get over yourselves! If the cop gave him a hard time, that's a completely different story - but as a hundred others have said, asking someone to interlace their hands FOR THEIR OWN PROTECTION is not a big deal!
Didn't your mother ever tell you? Better to be safe then sorry.
