It's not like the police chief can just pull names from a hat on a whim and decide "I'm gonna piss this fucker off today!", go get his toys and lets break em.
The point of that is that if you fuck up with airsoft guns, they have the right revoke your registration and seize your guns. I see no problem there myself. It's no different than a car, if you drive like an idiot you'll lose the license and possibly the car depending on what you did.
Handle yourself and your guns properly, and you have nothing to worry about. Just don't go out on your lawn waving them at the Black Helicoptors circling your house.
