Twin Cities Daily Planet brings our attention to this story: St. Paul cops allegedly taser and arrest black male for sitting in public space. City Pages provides some details: St. Paul police roughly arrest black man sitting in skyway
Note, this is hard to watch.
There are a number of transportation and land use and other aspects to this case which are worthy of discussion:
1. Do you have to identify yourself to the police? It depends. When driving yes – driving is a privilege. When walking (in Minnesota) no – “police can never compel you to identify yourself without reasonable suspicion to believe you’re involved in illegal activity.” Minnesota is not a stop and identify state, unless the police have “reasonable suspicion”.   
2. Is the skyway a public space? It is being patrolled by public workers (police), so apparently it is – though I am sure the law is vaguer than it should be – so the rights should be the same as on the street.
3. What are the details? The comment thread at TCDP suggests it starts near Caribou or Arby’s on the St. Paul Skyway System. He is going to New Horizons Day Care to pick up his child.
4. What happened after the incident – Charges were dropped according to City Pages. Did the police apologize to the man in front of his child? Was this incident expunged from his record? Did the officers have reasonable suspicion justifying their actions?
