Stories like this are why I receive alerts from Amnesty International. I wish there was something we could do. Writing a letter now and then really doesn't feel like enough.
I read about a police raid in NYC around the time of Stonewall where a young man panicked trying to escape a police station by jumping from an upstairs room to a roof. He landed on a spiked fence and was impaled there, still alive while they had to remove part of the fence in order to transport him to a hospital. The part about people being injured jumping from windows reminded me of that.
