Hopefully it won't even be on your record since the incident was dismissed (or rather, couldn't be used as evidence to support say a straight revocation should you accidentally commit an offense in the future).
I've had many conversations with our (Plano) local LEOs about armed citizens. There are lots of pro-ccw officers and even some who don't really like the idea but agree it's a citizen's right. Unfortunately I think every city has its share of anti-gun rights individuals that will do anything within their power (and often times beyond) to force their agenda on law abiding citizens.
Best of luck to you. And out of curiosity, did you contact that officer's superior and/or make a formal complaint with the department for both failure to copy you on the complaint to DPS & failure to make the complaint in a timely manner (5 days from what I read in the previous posts)? Even a "we'll review the situation" would let us know they are aware of the issue.
