NOPE!
Law Enforcement Officer - one who enforces the laws of the state. Have you so quickly forgotten that SCOTUS has even determined that our LEO's have no duty to protect? (i.e. - prevent violence) Now, I am a very strong supporter of our LEO's, and am in no way trying to bash this deputy. I believe that he did what he thought was right. However his thinking was flawed.
I'm not sure why RockofStrenght's post didn't garner a little more support, because I believe he said it best: (BTW, reps inbound once I reload)
I honestly can't believe some of the comments that are being made about this situation. The basic consensus of many in this thread is that the officer had the right to take the OP's liberties for the sake of "safety". But where does that road lead? Confiscation of firearms in a national emergency like Hurricane Katrina? Hopefully you can see my logic here. Yes it's just ammo. But where do we draw the line folks? If we forfeit our freedoms a little at a time, eventually we will have none.
I will summarize my belief in this situation with a well known quote by Benjamin Franklin: They who can give up essential liberty to obtain a little temporary safety, deserve neither liberty nor safety.
The reps are, as always, much appreciated . However, I have since altered my opinion to reflect the 4th Amendment's own clear wording. As the officer had a solid, reasonable purpose to continue to temporarily hold the ammunition he was not unreasonably seizing property.
INAL or a judge, but unless he broke some manner of lesser state law it is my opinion that the officer made the best possible decision in this case save that no receipt was given in order to guarantee the return of that property.
Yes, the unscrupulous and gun-hating in our society will attempt to use that logic in order to prevent anyone from being able to have and use firearms, among other freedoms, but unfortunately no human law has yet been written that cannot be twisted from its proper and useful meaning into a way to subjugate and control others.
