I wonder why the daily shootings and death tolls in some [Chicago] neighborhoods aren't enough to bring out the armored tactical units. Kids walking home from school are prepared for gunfire, people can't sit on their porches for fear of getting shot. That situation seems to me very similar to having a mad bomber on the loose.
The difference is in Boston they were looking for one individual whose identity was already known. In Chicago they'd have to be looking for hundreds and hundreds of individuals, not all of whom have ever shot their guns before so, according to the rules, they're free to walk around with them until the first time they decide to kill some kid for his jacket or miss and shoot someone sitting on their porch.
Somehow this does not seem like the best deal for the average person in Chicago, but a big show of force by the cops wouldn't last long enough to help much. Neither will it reduce the death rate to have the kids with the jackets and the people on the porches shoot back -- all you'd get is a lot of people enforcing their own agendas on one another. What's needed is a path to a community-supported police department, which is what we saw in Boston, and that would take undoing generations of distrust on both sides. It won't be easy.
