Chicago has some of the most restrictive guns in the country and among the highest rate of gun violence. Its proof more guns laws alone will not solve this. Other factors .. like the rampant mental health epidemic, the lack of enforcement against criminal activity, the decay of basic respect for human life etc are what is driving the problem more than gun laws.
Put something forward on the real issues and there might be hope of change. This lame blathering has already been shown to be essentially useless.
