Bratton, who pioneered the renewed emphasis on community police and the police review tactic known as "Comstat" to identify areas that need more cops, said Weis' plan is is the best method.
"That's tried and true American police tactics and it's the same thing that worked in L.A. and in N.Y. and in all likelihood will work in Chicago too," said Bratton.
Prof. Dennis Rosenbaum, a criminologist with the University of Illinois at Chicago, said that there might also be legal problems with the National Guard hitting the streets.
"They are just not trained properly to deal with this type of urban engagement," Rosenbaum said. "The National Guard is trained primarily for the theater where there is war and military units to respond to enemies."
"There are not enemies here necessarily. They're civilians and they are not trained in what the local police are trained in, like civil liberties," he said. "They don't understand reasonable search and seizure or reading people their Miranda rights."
"There are likely to be complaints and lots of problems."
