Delaware State Police (who knowingly violating constitutional rights) have agreed to pay $50,000 (cost of doing business) to resolve a federal lawsuit filed by a man who said troopers violated his constitutional rights by preventing him from warning motorists about a speed trap.

“I’m on the side of the road, legally parked, with a sign which is protected by the First Amendment,” Jonathan Guessford told troopers.

Dascham video shows Douglas twice lunging at Guessford to prevent him from raising his sign. Gallo then ripped it from his hands and tore it up

“Could you stop playing in traffic now?” Gallo sarcastically asked Guessford

As Guessford drove away, he made an obscene hand gesture at the troopers. Dashcam video shows Douglas racing after him at speeds of more than 100 miles per hour (160 kilometers per hour) in a 55 mph zone, followed closely by Gallo and Box.

After Guessford raised a middle finger at troopers while driving away from an initial encounter, he was stopped and cited for “improper use of a hand signal.” The charge was later dropped.

Police dashcam audio captures the troopers laughing and giggling at the notion of citing Guessford for using an improper hand turn signal because of the obscene gesture. “He wasn’t making a turn,” Douglas says.

“Is there a reason why you were doing that?” Douglas asked Guessford after he pulled him over.

Box told Guessford he was engaging in “disorderly conduct” and opened the front passenger door of Guessford’s vehicle.

“Take it to court. That’s what I want you to do,” Box replied after Guessford told troopers he was going to take legal action. Box also threatened to charge Guessford with resisting arrest.

“We’re going to take you in. We’re going to tow the car, and we’ll call social services for the kid,” Box said, referring to Guessford’s young son, who was with Guessford and witnessed his profanity-laden tirade against the officers. “It’s not a threat, it’s a promise,” Box added.

Box’s dashcam audio also captures his subsequent phone call with a supervisor, Lt. Christopher Popp, in which Box acknowledges that citing Guessford for his hand gesture is “pushing it.”

“You can’t do that,” Popp tells Box. “That will be dropped.”

“Yeah, it’s gonna get dropped,” Box replies. “I told (Douglas) it’s definitely going to get thrown out. … I said, ‘Ah, that’s not really going to fly, buddy.’”

Douglas is heard saying that even if the charge would be dropped, it at least "inconvenienced" Guessford.

Two first amendment infringements in one encounter though? This officer needs to learn what the first amendment is and how it works.
If the reason to have speed traps is to get people to reduce their speed then that guy was literally getting people to reduce their speed.
If the police wanted to enjoy their job they each would get a day to park a cruiser up the street … and then change into civilian clothes and sit in a lawn chair up the street drinking a beer smoking a cigar holding a sign saying “speed trap ahead” and then calling in anyone that ignores it with it being tracked by the squad car’s camera.

So, Douglass clearly isn't professional, but instead, takes pleasure in scaring the kid with social services, and towing Guessford’s car, and knowingly violating the constitutional rights of someone who annoys the police, because police have power issues, and have a sound clip on loop playing over their inner monologue "YOU WILL REPECT MAH AUTHORITAH!"

that's why NWA made a song, "Fuck the police" and ever since, many of us that outraged that police are determined to willingly violate the rights of citizen taxpayers, often repeat "fuck the police" as anyone that who commits a crime, while wearing a badge, is a shit for brains unworthy of the company of honest police who do the work to arrest criminals
