Interesting situation. What grounds did the State of TN use to justify a suspension of your CCW, especially as you were never charged with a violation of the law?
Also, I find the federal case to be interesting, especially regarding the defendants argument that the first officer who detained you let you go , even though he could "not could conclude that this weapon comported with a handgun carry permit," and "allowed [you] to continue walking, but kept [you] under surveillance" so he could contact Ward, his supervisor.
TCA 39-17-1351
(t) Any law enforcement officer of this state or of any county or municipality may, within the realm of the officer's lawful jurisdiction and when the officer is acting in the lawful discharge of the officer's official duties, disarm a permit holder at any time when the officer reasonably believes it is necessary for the protection of the permit holder, officer or other individual or individuals. The officer shall return the handgun to the permit holder before discharging the permit holder from the scene when the officer has determined that the permit holder is not a threat to the officer, to the permit holder, or other individual or individuals provided that the permit holder has not violated any provision of this section and provided the permit holder has not committed any other violation that results in the arrest of the permit holder.
I find it interesting to note that TN law requires that an officer, after disarming a handgun carrier during an investigatory stop, must "determine that the permit holder is not a threat to the officer, to the permit holder, or any other individual or individuals, provided that the permit has not committed any other violation that results in the arrest of the permit holder" before he can return a handgun to a permit holder and release him. I feel this is an important point.
Prior to letting you go, the first officer was, in effect, required by law to determine that you posed no risk to yourself or anyone else, and that you had not violated the law, else he would not have been legally able to return your weapon. By letting you go free and returning your weapon, the first officer in effect made the determination that you were violating no law and posed no threat to anyone. As he undoubtedly informed Ward of his action in releasing you, this nullifies one part of Ward's defense of his subsequent actions, specifically that his actions were due to "reasonable concern" for the "safety of the public", and that he was reasonably "suspicious that [you] were acting unlawfully." It will be difficult for him to articulate the reasons for his suspicions, having just received a report from a fellow officer of the results of the first officer's investigation which revealed no violation of the law.
You are foolish, IMO, if you think you can argue this case successfully in federal court on constitutional grounds pro se. Federal constitutional questions require great finesse to argue effectively, and you must get an experienced lawyer to help you, lest you get trumped on some obscure procedural grounds. Just read the recent opinion of the federal magistrate ruling against the Montana Shooting Sports Association bid to overturn the GCA if you don't believe how complex these questions are. I hope you don't think you are a latter-day Clarence Earl Gideon, because if you do, it is likely that you will be outmaneuvered by the opposing attorney, and lose before the evidence is even heard in court.
Having said all this, get a good attorney and best wishes for a successful conclusion to your case!
