The threat against law enforcement officers in Texas has now apparently spread to emergency personnel.
Several threatening incidents reported this week are under investigation.
On Thursday, a Houston fire captain stopped in his vehicle at a red light reported hearing a man in the back seat of an adjacent car tell someone: “t’s not a cop.” according to KHOU.
In an apparent unrelated incident the day before, four Aldine firefighters were eating lunch in a fast food restaurant when they were notified that a man was observed taking photos of them.
The witness said they overheard a phone conversation in which the man said: “Hurry, there are four white firemen here. I'll try to keep them until y'all get here."
Also in Texas, arson investigators reported a group of people making gunpointing gestures at them while making pig sounds.
Firefighters across the country are being warned to be on the alert.
