These records indicate that someone successfully impersonated the FBI in order to get me swatted. I was already aware this had happened but had to wait nearly a year to get the document that proves it. My reports to the Dallas Police Department about this have gone unanswered.

Imagine escaping the literal Nazis, making it to America, living three quarters of a century there making your life, and then this:
79-year-old Paul Bojerski was born to Polish parents in a WWII German refugee camp. His family legally emigrated to the U.S. when he was 5.
He’s been taken by ICE in Florida.

Paul Bojerski never gained official residency, but he checked in regularly with ICE for years. Then in July, at age 79, he was detained and sent to Alligator Alcatraz.

ICE agents in Chicago violently detain a non verbal autistic man for being “non compliant”
He couldn’t “comply” because of his disability…they don’t care
This is not the first time they’ve gone after a disabled person
They target the most vulnerable because it’s an easy way to meet their quota

In Chicago, a woman was driving to get coffee when a DHS vehicle fleeing an angry crowd crashed into her car. Armed agents jumped out of the vehicle, yanked her door open, pulled her by the legs out of her car at gunpoint, held her incommunicado for hours, then released her with no charges.
