jury rig it to fire actual bullets and use it to kill those littering hooligans who threw it into your yard
The gun says not to modify it, i can't go against a warning on a plastic toy
obviously it was involved with a crime
report the gun to the police and give them a description of the kids
I didn't get a good look at the kids that would allow me to describe them in detail, but anyway, the gun doesn't show any signs that it may have been involved in a crime, there's no blood, dirt, unusual prints or scratches
I think at most this could have been stolen from a baby...
