ATF data

Been looking at the ATF 2012 trace data for my state, Maryland.

The vast majority of traces were guns sourced to Maryland.  And the vast number of traces that were done on crime guns were purchased more than 3 years prior.

Average age of possessor was 40.  The national average is 36.

The Maryland city with the most traced guns is, surprise, Baltimore, with more than 50%.  My burg, Silver Spring, had only 150 traces.  Silver Spring abuts the District of Columbia on the Georgia Avenue corridor.  That's the east side of Rock Creek Park.  West of the park is Connecticut and Wisconsin Avenues.  That area is more affluent with suburbs abutting you may have heard about.  Bethesda and Chevy Chase.
