Also in Italy, they want to come into your home and throw everything upside down, and search, they can and they do. They don't need to show you papers at the door.
They don't have to go thru endless amounts of paperwork to tap a phone. They'll throw a whole fucking tap down an entire street if they want. They will come in and arrest your mother, wife, sister, brother if they want to get to a family member. They convict and sentence you in absentia if they say you're guilty.
They arrest you and hold you until YOU can prove there isn't enough evidence against you to hold you and try you.
