So here was the situation I was in about a month ago. The animal control unit from Grant county came by to take my dogs because they killed my neighbors dog. All evidence says the dog was run over, not mauled. Anyway when the LEO made contact with me I had my Kimber in my leg holster as usual. I put my hands around the back of my neck to show I had no intention to draw. The LEO then approached me and without asking removed my pistol from the holster and placed it in his vehicle. When he was leaving he said he would put it on the real estate sign at the end of my driveway. Now I know I did some things wrong here but I don't know where to go from here. I'm still trying to prove my dogs are innocent and get them out of jail.
You could sue him for reckless handling of a firearm, because to take your firearm and put it on a sign which was (x) distance from you, allowing someone walking by to grab it and shoot someone, steal it, etc. is negligent, as well as reckless.
In fact have your lawyer send him a letter with those facts and see what happens.
Oh, I presume:
1. You were not on your own property;
2. You invited the deputy onto your property if you were on your property;
3. You were running a recorder during the encounter;
4. You took some pictures of him, his cruiser, his placing the gun on the sign, a pic of the gun where he left it, or something like that to offer as evidence you didn't just dream this.
If you did none of the above, then 'where you should go from here' is you have learned a couple of valuable lessons. Unfortunately your dogs may pay for your carelessness with their lives. In cases of 'dog problems', I blame the owner not the dogs. You may have been innocent of this crime but it looks like you are careless in handling your canines.
1. Always be running a voice recorder (or vid and voice) when OC-ing, even on your own property;
2. Gather evidence when stuff like this happens, (similar to taking pics of a traffic accident, position of cars, etc. so you can show it as it happened and you appear to be trying to be honest, show truth);
3. Keep your dogs in a pen, tied up, on leash;
4. Gather evidence on the mauling case in a similar manner.
Often times, a minimum of 'evidence' (not proof but something besides a person babbling something) can win you a case, or even prevent one from happening. For example if you whipped out your vid cam when the deputy was leaving and zoomed on him leaving your firearm right out in the open near the street, then they'd drop all charges and go hide under their desks. But I suspect you didn't do any of this. That's called 'due diligence'.
Finally, sorry this happened to you. Live and learn, eh?
