Woman arrested, accused of threatening a shooting at East High School

Notes:

  • Alexander was an illegal alien, a so-called Dreams. Dreams of mass murder.
  • She posted using a alias. Yet the Rochester Police Department still tracked her down and took action. See what a competent police department can do, as opposed Sheriff Israel’s clown posse in Broward County.
  • Alexander weapon of choice was a shotgun So much for the CNN idea that confiscating all AR-15 style weapons would magically eliminate school shootings.
  • At twenty-one, what was Alexander doing in this country and in high school?
