911?!

Last night, my mom called 911 because there was suspicious activity next door and there was a motorcycle rider without a helmet. When the cops come, they try to arrest HER! They said it was misuse of 911, and that they were going to make an example of her. How would they be making an example of her when the only witnesses were our other neighbors that she was sitting with? They were really rough with her as well, hurting her bad knee and her shoulder. They wouldn't even let her go lock the house, or get shoes, or her ID, or anything. They wouldn't even let the good neighbor go and get my mom's phone to call my dad. My mom has panic attacks, anxiety problems, and a severe mistrust of cops. By the time everything is sorted out and they let her go, she is sobbing and shaking. On of the cops even kicked my cat as he walked by!
