Lets face it, these days brandishing any weapon around Police officers
in the line of duty can get you killed. Brandishing any firearm "toy or not"
during a dispute call is just asking for it. That man is lucky it was only a leg.

Disguising a firearm to look like a toy would be a state by city issue.
And probably earn you a well deserved face plant in the concrete if
a Cop catches you with it.
