Do you feel the National Guard can help in areas with high crime?

The NG would provide a temporary measure of public safety. It would be a short term fix. Due to the racial and socioeconomic issues in Chicago, this would be a PR nightmare for the Guard (and Army in general) and would show a heavy handed measure by the state government that may only raise tensions.
The appropriations spent on such a deployment would be better used to help fund a long term solution. Chicago needs changes in its political culture, dependence on government assistance, family life and economic policies. Chicago is a great city and deserves more than a short term solution of soldiers patrolling its streets. The deployment of troops should be reserved for situations where civil government has either completely failed (broken down/dissolved) or a man-made/natural disaster has expanded beyond the capability of the local/state government to respond.

There is no shortage of cops in Chicago. Crime is persistent because the culture and family systems in the area have broken down to the point that success is the exception, and not the rule.

As Guardsmen, part of our duties is to augment local and state government. Some of us are tasked with NGRF, National Guard Reactionary Forces to augment local law enforcement for civil disturbance. We are deputized by law enforcement. First level of any police department is officer presence. We assist with presence patrols. High crime areas are usually high crime areas, due to lack of police manpower. If you have a large number of troops to pool, your force multiplies. It offers extra eyes and ears to law enforcement. I've worked for the inauguration in 2012, and we've done health and welfare checks during disasters. If we can be used to direct traffic, so a department has the manpower to respond to crimes of a more serious nature, I'd definitely say that is beneficial.
