Remember the ethnic Arab academic, Steven Salaita, an American born citizen who couldn't help broadcasting anti-Israel social media 'hate speech'  in 2014, sample:

"Zionist uplift in America: every little Jewish boy and girl can grow up to be the leader of a murderous colonial regime."

"If (Israeli Prime Minister Benjamin) Netanyahu appeared on TV with a necklace made from the teeth of Palestinian children, would anybody be surprised?"

Marco Rubio, from interview with Marco Rubio in the UK Guardian:

“The only way to defeat Isis is for Sunni Arabs themselves to reject them ideologically and defeat them militarily,” Rubio said. “They must be defeated on the ground with a ground force that is made up primarily of Arab Sunni fighters from Iraq, from Syria, but also from Jordan, from Egypt, from the Emirates, from Saudi Arabia.”

Exhibit One on why it will be a very uphill battle to reduce cop shootings. Dr. William J. Lewinski, 'psychologist' from the Force Science Institute. Teaching cops the 'science' of why they must kill in the blink of an eye. The guy you never heard of unless you were on a jury deciding the fate of a killer cop.

NYT Training Officers to Shoot First, and He Will Answer Questions Later.

A 'scientist' profiled in the NYT and a huge success in cop circles, with a million subscribers to his newsletter.  His 'research' is published in non-peer reviewed magazines.

I am not a fan of gun battles like the recent biker shootout in Waco, but they may be an inevitable, and possibly legal occurrence in a 'stand your ground' state.  The first biker to threaten another biker or his property with harm, if found, may have broken the law.

After that initial disturbance, a chain of 'stand your ground' actions, self-defense actions seem to have occurred. It is legal under Texas law, see below, to use lethal force to protect yourself, other threatened persons, or property. There is no requirement in the law to back down or retreat, anywhere, even a public place.
