NEW YORK (CBSNewYork) — The de Blasio administration on Monday was trying to ensure that peace is maintained the Staten Island rally for Eric Garner – the man who died in police custody last month.

As CBS 2 Political Reporter Marcia Kramer reported, the mayor wants to avoid violent confrontations with officers like those that have transpired in Ferguson, Missouri, after the police shooting that killed Michael Brown, 18.

As of Monday, a bouquet of flowers and a few candles stood at the Tompkinsville, Staten Island, site where Garner was taken down in a police chokehold and later died. Along with them stood a cardboard sign reading, “From Staten Island to Ferguson, MO, no justice, no peace till the killers of Eric Garner and Mike Brown go to jail.”
