Have you talked to the police department? 

Its common to give discount for law reinforcement personal. even better if they can park the police car onsite. 

He called me last night to let me know what had happened and that he had filed a police report but couldn't get a hold of the mother because she was working.The mother works all hours and the boys are being looked after by their teenage sister.My question is: Is any of this my responsibility? 

The police found him death after almost a week.

I've been a Police Officer for about 15 years, I'm married and have 4 awesome tax credits.....er, children, and no pets.

You can do this on https://www.communitycrimemap.com/ -- this is the site the Stockton Police Department directly uploads their crime data to per the local government website.And mainly, you want to avoid violent crime.

For instance, at the far limits of what this society tolerates in terms of violent behavior is the local police and their weaponry.

But note - these maps are updated WEEKLY because they have so many hits: http://www.ci.minneapolis.mn.us/police/statistics/crime-statistics_codefor_shotsfired 

Tensions between local police and some segments of the city's population run very hot.

I will be quitting my job in California as a Police Officer and moving to Las Vegas!
