Bricks from a 20 story building on the Upper East Side crashed through scaffolding Friday, injuring a 72-year-old man.

"Scaffolding is supposed to be there to protect us from falling debris, now it's actually not stopping items from hitting people," Councilman Ben Kallos said.

Kallos started battling for tougher scaffolding rules after November's accident in SoHo, when a so-called sidewalk shed colapsed, hurting nearly half-a-dozen people.

Kallos said his bill is running into some walls of its own.
