About a decade ago, NYC victims were compensated for being arrested under a "vague loitering law" which a federal court deemed unconstitutional. Ever since municipalities have re-written their loiterring laws to be more specific and often deal with a specific criminal offense.
My municipality (Seattle, WA) has drug loitering and prostitution loitering laws.
If I were to sit peacefully in the cafeteria of a public hospital to use the free wifi (Harborview) and refuse to leave under constitutional grounds, could I be arrested? I can't be trespassing on a space open to the public at a public hospital- can I?
