This is wrong on many levels. Why target Eastern Europeans? Why of all "crimes" homelessness?

Because as EU citizens, we know we are not allowed to visit another EU country for more than 3 months. We can't just simply move to another EU country.
If we want to stay longer than 3 months, then we have to be exercising treaty rights and be a qualified person and then meet the rules for the type of qualified person we are i.e. be billed for our healthcare while in that EU country. Living on the streets, homeless, is not counted as being a qualified person under EU rules.
Just like all immigrants, we also have to abide by the laws of that country.
I doubt they targeted just eastern europeans, but perhaps the ones they found sleeping on the streets were eastern europeans?
Germany is putting through some tough new laws on immigrants, even tougher than the UK's new Immigration Act and new strict welfare reforms.
