You know, everyone is assuming that the police are going to do a full tactical response with SWAT teams, helicopter support, body cavity searches, etc., based on the fact that you call them to inquire about disposal of found ordnance.
That's not going to happen unless you let it.
There would be absolutely NO probable cause for a premisis search, anything found in a forced premisis search in such a situation would be inadmissible.
If you're too paranoid to actually call the police to your home about somethign like this, gently put it in a box and take it to the police!
In fact, if you're that paranoid, what are you doing talking about guns on the internet? Don't you know that "The Man" can track you that way?
I've DONE THAT TWICE in small town Pennsylvania.
My home wasn't searched, I wasn't arrested, I wasn't put on a terrorist watch list, I wasn't given the third degree with a car battery and jumper cables hooked up to my testicles...
The officer asked where it came from, I told him box lot of junk at a farm auction, and that was that.
This crap shows up all the time all over the country. They're NOT isolated instances.
Police would much rather you call them than randomly try to ditch it.
Some of you really need to stop watching to many bad movies on TV. They're fueling delusions.
