I don’t think that’s true at all. I looked at every police set Lego is selling currently and not a single one of them included even a suggestion of a gun.

Typical police equipment are handcuffs, megaphones, walkie-talkies, traffic paddles and coffee cups. The criminals might carry gold, banknotes, dynamite or crowbars and other tools.

The most gun-like thing in current sets is the huge net shooter (larger than a minifig and not portable at all) that really isn’t very gun-like at all.

Not even the minifig prints include suggestions of guns.
