Stop saying "rubber bullets" they are BLUNT FORCE ROUNDS
"Rubber bullets" is a euphemism used by the militarized police industrial complex to get away with beating people at range for no reason.
They are intentionally designed to injure.
These are not toys, the manufacturers still consider them potentially lethal. The rounds carry significantly more energy than a fist, closer to a hammer.
Cops shooting people with them is like hitting people with hammers.
