In the 1990s, when I lived in central-NOVA(VA), I heard of a major politico wanting to station or deploy uniformed Washington DC National Guard troops in HMMWVs(hummers) WITH weapons to fend off drug gangs & armed thugs.
Was it Newt Gingretch(the US Speaker of the House)? No. Rush Limbaugh? No.
It was the Washington DC Mayor(an elected official) Sharon Pratt Kelly!
Many US citizens do not understand the PCA or Posse Commitatice Act(check spelling). These US laws were set up to prevent excessive military actions or LE in CONUS or the Continnental United States. These were valid, IMO to prevent the country from becoming a armed camp or a police state but in the post-9/11/2001 world, military tactics, weapons & uniforms are now more common.
