But that's not to say they were shocked.
For many weeks now, residents, led by Jerry Blackshear, a retired police sergeant turned community activist, have been complaining about the city bringing scores and scores of homeless men into shelters in the community.
Blackshear and others have been especially concerned about the Sumner Avenue armory, located just a few blocks from where a crazy-eyed man beat and stabbed the bus driver.
Up and down Jefferson Avenue and on the side streets, in the shadows of the armory, residents have been complaining lately of homeless, jobless men entering the front yards of brownstone homes, sometimes to urinate or even defecate, or go through mailboxes.
Blackshear says the elected official most involved with her in the effort to ease the situation is Borough President Marty Markowitz. (see previous BrooklynRon post.)
Blackshear says she would like the city to use some of the space in the cavernous Sumner armory for community projects, as a meeting place for seniors or as space for training area youngsters in the culinary arts.
It's being reported today that police have arrested someone in the killing of Edwin Thomas. The killer allegedly had entered the bus with an invalid metro card, asked for a transfer and then when Thomas refused to give him a transfer, he beat Thomas and then fatally stabbed him.
