I went to the Austin gun show . A guy walks up to me and asked " How you been ?'' I looked at him crazy and said somthing like I am not from here . The guy then asked '' weren't you in the fed ?'' meaning the pen. I told him that I was never locked up at any point in my life. I walked on . I left hours later with 1000 rnds. of .223 that I purchased .I brought my 9mm along to look for a good holster for it . My gun still had the zip tie on it . I was dropped off /picked up by my friend because I knew the parking would be too crazy ... I was right . After getting food to go we were pulled over by three APD. We were given the " felon with a gun treatment'' . The APD was called by the ATF to detain me while they stood aside and looked on. I was cleared over an hour later . ATF said their ex-con snitch told them I was in the federal pen before and they jacked me up on this basis. I was free to go but I can't help but be pissed that they would violate my rights like that ... be aware the ATF is under cover at all gun shows if did not allready know this. I was wronged big time !!!
