When lawlessness is ignored and accepted at all levels of government the people at street level have no fear of the law.
From the White House and Congress, the Federal bureaucracy down through state, county/parish and local government there has been a dearth of lawful behavior the past 20 - 30 years or more.
And we have allowed a steady stream of invaders from countries with even more corrupt and lawless governments than our own, unbound from the harsh and often violent response from their home countries' law enforcement they operate here in a utopia of unchecked mayhem.
Houston appears to be the poster city for what the progressives/liberals want the country to be. Of course as long as they, the elites, have their armed security to protect them.
