Quick Steel,
Thank you for the post/link. Nice clean read with common sense suggestions.
I'm sure there's always room for this or that, but I believe your buddy covered a nice spread.
I'd like to follow up on a few things where he wrote: "Its not a bad idea to copy and carry those regulations with you, perhaps in your car, to politely show an aggressive LEO.".
I'd also suggest that a person carry a published description/spec sheet on the knife being carried (I do this only with knives that look iffy). It's especially helpful if there's confusion as to blade length, A/O, etc... .
Also, don't be afraid to promptly write up your own incident report of what took place with the officer (include date/time, etc...). If/when it gets to court, written reports will more than likely be referred to and may be relied on. It may not be your word against the officer's, so much as it might come down to your word/recollection versus a document prepared shortly after an incident, recording fresh memories. Civilian/citizen written accounts do matter.
Another thing I would recommend is have any/all witnesses write down their own report/s of what they saw & heard, if possible. Provide these to your attorney or submit these to the court yourself, along with your own report. Btw, bring/provide that published description/spec info I mentioned earlier. If you do submit this stuff yourself, provide multiple copies (for the Judge, Deputy DA, etc..., if it wasn't already done before the court date).
There's other stuff to keep in mind, but that's only if things got a little rough with the LEO. Please PM me and I'll be happy to provide a little more info, in layman's terms. While I'm not an attorney, I can provide you with my CA background.
Hope some of this stuff helps.
