Are the rioters buying these or the people and shop owners who want to protect their property?
(UK poster here - living away from the riots though, thankfully) There was apparently a decently large group of Turkish business owners in London last night who got together with baseball bats to protect their businesses (which apparently worked). I'd say it's a bit of both.
Guess Turks have more of a right to be there since they actually protect their land.
