You can get stickers like that anywhere that does decal style printing. Custom made anything.
That deflates some last hopes for people.
However, except for falsified records, is there a record of this guy actually ordering and paying for the big decals at a custom place? As on M Squad, Untouchables, Dragnet and Adam -12,
will there be a guy at a place to say
“Yeah. I seen him. Jeez he was weird. One of dem Trump crazies, ya know? Paid in cash. I don’t keep no records or receipts here. I seen him on the TV news and knew that was da guy.”
