"You have the right to remain silent during a traffic stop." Yeah. Sure. You try that and let me know how it works out for you...after your car has been disassembled, all its upholstery ripped, and put in impound. After you are released from jail exactly 47.9 hours later, or charged with "interfering with the duties of a police officer" or "obstruction of justice" or "causing a public disturbance (which may or may not be dropped by the DA. Or thrown out at your hearing the next afternoon, by the judge.)
"If your rights are violated while being arrested, take notes" - with what, exactly? The pen and paper the people who violated my rights gave me? These people live in a alternate reality.
The ACLU has no concept of what constitutes practical advice for dealing with abusive police or the issues the vast majority of Americans face when stopped by an officer...like ending up in jail and missing work the next day, your car destroyed, and being summarily fired for failing to show.
Congrats! You are now unemployed, with an arrest record, probably your name in the newspaper police blotter, and a bunch of legal expenses from the trumped-up charges.
But hey, you followed the advice of an organization that will do absolutely nothing to help you after you followed their instructions and it caused you to end up unemployed, in debt to an attorney, with no wheels...then homeless because you missed your rent.
I don't think a single person at the ACLU has ever had to worry about having enough money to buy groceries, lived one paycheck away from missing rent, or worked a job where if they didn't show up for a shift on time, they were fired.
