The most famous eviction was the two efforts to clear East 13th Street of squatters in 1995. For more than a year the buildings were kept under 24 hour guard by NY police to prevent a re-squat. The squatters were jerked around in court and the buildings became housing developed by one of the nonprofits. If you'd like to look thru my files let me know. I'd be happy to oblige.
Public opinion varies.
I think it was most favorable in late 80s and early 90s. I don't think the public even thinks about squatters and I think most squatters are comfortable with that. Today I learned that the City has decided not to appeal. Soon there will be a special hearing to determine the amount the squatters will be awarded. This will be the first time squatters will be compensated following an illegal eviction.
