several people have noted this, but it isn't generally illegal to modify the appearance of a toy to appear to be a real firearm. it is a requirement for a blaze orange tip to be present for import on such toys to the US, as most states require it for sale, but the end user can do whatever he wants to it, including painting or removing the blaze orange tip.even though it's illegal, Phil would still do it because fuck da police
some states (California) and some cities (Chicago) have additional special requirements like fully transparent bodies, obviously toy-like colors like neon green, and a variety of other features. San Francisco and NYC specifically forbid possession of airsoft, pellet, paintball, and similar devices entirely. but these are example of the exception, not the rule.
what i really think will happen as far as legalities with Phil is he's going to convince someone else that his toy AK or whatever is a real firearm. attempts to commit a crime with a toy firearm treat the toy as if it's the real thing, ergo if he's pointing it at people or tries to walk around with it, he'll catch a brandishing charge.
maybe next is independent transportation? will 2019 be the Year of the Bicycle?
