Its real fucking simple and I keep telling this over and over...
Dont.... resist....
Get arrested, get locked up for a day, if you have done the crime do the time, if you didn't sue the deparment what ever.
Dont.... resist
Dont talk back
Dont argue
And I have been arressted a lot of time by German cops, never fought with them, never made a big deal, never tried to run away, gave my hand got handcuffed walked out told my girlfriend to go home.
Its that simple.
NOW...
If you want to have it different you can, but it's going to hurt.
