Thanks for the reply and sorry for the delay. I was finishing with another customer.
I don't think any of this would automatically rule out a probation possibility. Especially if he got himself beaten up pretty badly, he may actually turn out to be a sympathetic defendant.
If this just happened you need to get some photos of your son's injuries because he might also have a brutality suit that he could file, depending on what the facts show, and he doesn't have a great deal of time necessarily, to put the county on notice that one day he may sue. This is something he needs to take up quickly with his lawyer.
The fact that he's a flight risk may be more of a deterrent to a probation offer than the fact that he kicked at an EMS worker when he was obviously tired of being manhandled. So it's very important that he keep his court
There are specialty courts too involving probation, for which he may be eligible. If he has mental health issues, for example, undiagnosed or otherwise, that keep him from being able to control his anger, or substance abuse problems that could account for a lack of self control, the courts have treatment oriented probation options too which could help with his case and also to give him the tools he needs so that he can avoid something like this.
