I feel that civil rights are still strong and well respected and generally these things shouldn't happen – so that perceptions is still accurate. Maybe not that much in Bavaria, but natinolly still, yes.

About the more technical legal question: I think – as some other commenter pointed out – the legal basis for the search should be the same. The searches themselves should be governed by the respective police law – in other states the police would be a little more restricted in how to handle the searches.
