i would think any reason to help keep the peace or just to even out the playing field if you are in a situation to where you feel that you are in fear of your life should work?
heck,after i took the training course,or class..what ever ya wanna call it...went down to the sheriff's office and got finger printed and paid my fees...about 4 weeks later,the sheriff called to tell me there was a little problem with my app. wtf? is what i thought?..he asked me,when and why did you assault a police officer?i was like OMG! i was so shocked to find out that somewhere in my punk youths years, i was so high on grass that i did something so disrespectful...and dont even remember doing such a thing...i was tault better...my old man used to say..you can fight the law...but you have a better chance whooping your shadows a**
...but that has always been my number one rule in life...so anyways,i just knew i would never get my ccw...but after talking to the cool sheriff, he approved my permit and i was one happy camper
...of course the reason why i was asked about the assault charge...they had got my paper work mixed up..so if your denied...it dont hurt to ask why?...good luck
