With all due respect to tarazkp, nobody, without a shred of proof other than their word, is going to believe:
"These groups dressed in mostly black and with shaved heads, were made up of many convicted rapists and perpetrators of domestic violence."
Granted you can see a shaved head but often are not privy to their actual identification let alone their police record unless written about or published, and only those with a counter agenda to the whole argument, is going to go to the extreme that one group is just the same as the group being accused, of which I'd state, there is no way to prove the other group is any less or more behaved. It's not even a worthy talking point in the whole immigration debate. It would be akin to taking Trump's word that they emptied out their prisons and sent their people here. I am sure some bad people came here, but I also believe that's been going on for a long time, there's always going to be bad apples in every bunch.
