instead of going rampant on the police officer, lets think about it. what could possible cause this?

1 - a wii-mote accessory in the shape of a gun. it could be black.
2 - the young guy opened the door too quickly, violently, and startled the cop. (for your information THIS ALREADY HAPPENED TO ME ONCE - during a paintball game, when i returned to our base, i was unsure if it was still being used by my tam of conquered( we didnt have microphones at the time) and when i went there, a guy opened it too quickly, and i instinctively fired... into my CO. he was NOT pleased.)
3 - bad lighting / a strange noise e.g. un-ataching the Nunchuk or something could resemle c*** a gun.
4 - something in the guy's attitude scared the police.
5 - a mixture of the above.

so, we know that there was no weapon found in the crime scene.
the wiimote colour is not specified.
accessories are not specified, so this could make point 1 void. (i believe that having the wiimote in a gun prop for Call of Duty or something would be relevant enough)
point 2 COULD have happened. people can get nervous. but i doubt it alone would make the police panic and shoot. (assuming thats what happened)
point 3 seems pretty valid. if i heard something like c*** a gun, i would deffinitely shoot first. however, its not that much of a solid chance, since policemen have pretty decent training with firearms, and i am pretty sure they can distinguish c*** sounds from other similar ones.

draw your own conclusions, but i think it was a mix of everything.

It wouldn't have made a difference what the kid's attitude was because he didn't even get to say a word. Remember, the cop

why don't you go up to those cops and tell them who's boss instead of cry on computers
