Between 1992 and 1994, they virtually eliminated the homeless population in Rio De Janeiro. I was in shock. People talked about it in whispers but they were foreably relocated. if they came back, they were eliminated. Others they didn't round up were executed by different varieties of hitmen and military police.
There were thousands in 1992. There were 2 in 1994. I have never forgotten this and it haunts me more with each passing year.
