Believe it of not, you can still do that in states that aren’t run by petty fascist motherfuckers. Town I grew up in doesn’t even have school busing, so it’s normal that kids walk to/from school and activities, and no cop would look twice at a school-age kid who’s outside unless the kid looked hurt. (The town also put out a warning to parents not to drive kids to school if possible in the local paper — they said it increases traffic and endangers pedestrians.)
And I wish nothing better than a slow, agonizing case of MRSA of the soft parts to the cops and CPS assholes who tormented that poor couple in Maryland. So glad they won in court. Hope they own the police department and CPS by the time the lawsuits are done flying.
