POM is what I carry for in between the harsh words and a firearm, as I once heard about carrying OC. Youtube videos show POM it is pretty much as effective as any other, if it reaches the face.
Random thought I was discussing with a friend. If you have to spray someone what are your obligations to stay on scene? I would be inclined to leave the area and return home and put away the groceries. Call 911 on the drive and tell them what happened and I left the area due to safety and if an officer needs to speak with me come to my house.
I was a just a random person involved in an a motor vehicle accident that involved an unsecured load and no injuries. 10 minutes elapsed before police arrived and the total time on scene was nearly an hour for paperwork.
Sucks to ruin a good portion of your day when an incident evolved involved someone who decided to go crazy and FAFO...
