"F-K TRUMP AND F-K YOU FOR VOTING FOR HIM", screams the windshield-sized decal plastered on the back window of a pickup truck belonging to Karen Fonseca, 46, and her husband.
On Wednesday morning, Sheriff Troy E. Nehls of Fort Bend County, Texas, posted a picture of the back of a truck asking members of the community to help him find the 'offender'.
Nehls said Wednesday that the message could cause offense and raised the possibility of a misdemeanor disorderly conduct charge.
The county sheriff says he received complaints about the sticker and it may be illegal.
Fonseca, who has children, said she's heard the criticism from some parents. "I don't want to see anything happen to anyone". She said there was "no particular reason" they chose to stick the message on the back of the truck.
"Interesting... your cop cars have "in god we trust" smeared all over them - can I file a disorderly conduct against you?" another critic wrote.
And the Internet responded swiftly as thousands of commenters flowed in offering relentless trolling, thoughtful defenses of free speech, and cutting rebukes of partisan hypocrisy.More news: Roger Federer feels Alexander Zverev is the 'full package'
Others said the language used in the sticker was just as graphic as previous statements from President Donald Trump, alluding to 2005 tape, where Trump spoke to former NBC TV personality Billy Bush.
Speaking about the message, Fonseca, 46, told the Houston Chronicle: "It's not to cause hate or animosity".
"The sticker has attracted attention many times before, Fonseca said".
But the ACLU cited a 1971 Supreme Court decision, Cohen v. California, in which the high court overturned a man's disturbing-the-peace conviction after he'd gone to a courthouse in Los Angeles wearing a jacket that said "F-- the Draft".
A Texas sheriff says he could throw the book at a driver over his limited vocabulary and dislike for President Trump. "It's just our freedom of speech, and we're exercising it".
But the Facebook post was removed Thursday as a First Amendment controversy swirled around Nehls.
"Anybody traveling down the road that is behind that truck may have voted for Trump [and] that is where we might see a breach of the peace", the sheriff explained.
