I'd say that it's about time for some smashed windows. At night; no need to put anyone at risk with the warning shot.

If any of the groomers have photos available, print them out, take them to the range, and put a bullet hole between the eyes, then tape the picture on the school's front door.

The principal and the school board members and the other groomers and groomer-enablers have home addresses. Someone knows what those addresses are. Find them and leave notes under their car windshields, go through their garbage cans, take pictures of them and their families at home and mail them the pictures.

Like I keep saying, I apologize for nothing. The US government gave me training and experience in subverting corrupt and tyrannical governments. Cryin' shame that this knowledge is useful at home.
