Shooting in Brooklyn reveals a couple of problems.

via the New York Post:

A pregnant 34-year-old Brooklyn woman walking home with her child from school was fatally shot as she bravely shielded hers and other children when gunfire erupted on a Brownsville street today.
Bullets also struck an 11-year-old girl and a 31-year-old woman who was walking out of P.S./I.S. 298 with her own kids right after dismissal at about 2:35 p.m., authorities said.

1. The most obvious problem is that New York's strong gun laws and New York City's even stronger gun laws did not work. Licensing, registration, magazine limits, extraneous background checks... They all failed.

2. New York City's defacto prohibition on carrying firearms for self-defense ensured that the shooter had a target rich environment. The New York City government did their best to make sure that there was absolutely no chance that anyone could fire back and in turn force him to abandon his "mission".

3. Gangs are the problem, not people who go through the process of getting vetted and licensed to carry a gun, Mr. Schneiderman.
