Automated License Plate Readers (ALPRs) are AI-powered cameras that capture and analyze images of all passing vehicles, storing details like your car’s location, date, and time. They also capture your car’s make, model, color, and identifying features such as dents, roof racks, and bumper stickers, often turning these into searchable data points. These cameras collect data on millions of vehicles—regardless of whether the driver is suspected of a crime. While these systems can be useful for tracking stolen cars or wanted individuals, they are mostly used to track the movements of innocent people.

That's easy to remove. It would be really sad if someone slapped some etching cream on the lense though. That's a non-removable, chemically permanent change to the glass.
Is scary as hell to me
Hydroflouric acid dont get it on you
Our chemistry teacher warned us about this stuff. She told us that if you get it on you, don’t hesitate to call out immediately because you will not feel anything and think you’re okay until it’s too late and under your skin. And then it burns. So, so much worse than if you had washed it off right away.
Plus it'll dissolve your bones faster than your flesh
That’s a fun fact I must have forgotten!
Depending on the amount in your body it can very well be deadly. too.
I used this in 8th grade to etch glass for art class.
It's not as bad as all that. Just wear gloves and if you get some on you, just rinse it off.
It won't start dissolving your flesh or anything and needs time to even etch the glass.
Hey, you wanna fight fascism, you gotta get some PPE. Plain-as.
Time and resources wasted ain't nothing and you can spray the foam from a bit of a distance.
I had the same thought, but I assume the lens would have a coating this wouldn't harm.
