Anti-Nazi protestors? Or Nazi protestors? I'm confused by this, it was my impressing that being a nazi (neo-nazi) sympathizer in Germany was illegal in the first place. Seems like a weird group to be angry about if they are Anti-Nazi protestors as the page claims.

Is that incorrect?

Anti-Nazi.

There's some light(?) political right bias in some parts of the German police.

I'm not saying that german cops generally are nazi sympathisers but you're more likely to meet a right leaning cop than a leftist one.
