Quick quiz: What type of people were banned after the Tyler poison gas massacre?
Oh I'm sorry, Tyler poison gas plot...
The Tyler poison gas plot was an American attempt at domestic terrorism thwarted in April 2003 with the arrest of three individuals in Tyler, Texas and the seizure of a cyanide gas bomb along with a large arsenal that included at least 100 other conventional bombs, machine guns, an assault rifle, an unregistered silencer, and 500,000 rounds of ammunition. The chemical stockpile seized included sodium cyanide, hydrochloric acid, nitric acid and acetic acid.
The three individuals were linked to white supremacist and anti-government groups. They were:
William J. Krar, originally from New Hampshire
Judith Bruey, Krar's common-law wife
Edward Feltus of Old Bridge, New Jersey
Feltus was a member of the New Jersey Militia. Krar was suspected of making his living travelling across the country selling bomb components and other weapons to violent underground anti-government groups. Federal authorities had their eye on Krar since at least 1995 when ATF agents investigated a possible plot to bomb government buildings, but Krar was not charged. Since the September 11 attacks, their attention was focused on Middle Eastern terrorist activities. They were only alerted to Krar's recent activities by accident when he mailed Feltus a package of counterfeit birth certificates from North Dakota, Vermont, and West Virginia, and United Nations Multinational Force and Observers and Defense Intelligence Agency IDs. The package was mistakenly delivered to a Staten Island man who alerted police.

So, Trump wants to blame Robart if there's a terrorist attack by a refugee? OK, does that mean we get to blame the Trump Administration if there's another Adam Lanza, Dylann Roof, Jason Dalton, or William Krar, but they were too busy investigating dark skinned people with unusual beliefs to even stop them?
