M immigration has infected the homeless now, what next?

i just stopped 2 fellas beating up on a homeless, the one being beat up was a well known local homeless the ones doing the beating were two immigrants and they wanted his spot on the high street which the local wouldnt give up, saturday night blokes out with their women he could make a few quid. begging and being homeless on the streets isnt a cottage industry, its not a reason to immigrate but obviously to some it is. the only reason why i stepped in is because i recognised the fella getting the beating, romany gypos have a good one where they beat up on somebody a perby steps in thinking 2 against one aint so bad, but of course the one getting the kicking is in on it so now its 3 against one. whats the lowest a criminal immigrant will sink to for easy money?, i know all the scams and cons. but beating up a homeless for his beggin is a new one to me. how low can they go?
