Its a silly idea even from a safety aspect.
You think criminals wont know? Pretty sure a big idea like this will make the news. So now, when someone kidnaps a child, they will be sure to take out a razor blade and cut out the chip installed in them. Simple as.
Thatll be pleasant, im sure.
You know, on that note.. and this note..
Itll be nice when one of us is captured, and the bad guy uses a spork to dig the chip out of your skin.
Do you not instantly think that whomever captures you, isn't thinking of killing you to begin with? I mean, lets be realistic here.. NorCal, you aren't Chuck Norris, and this isn't Missing in Action, or Delta Force. If you get captured, I'm pretty sure if they had something as sadistic as ripping open your flesh to dig out a tracking device.. they had thoughts on making you squeal to begin with. If not just killing you, out-right, once they finished getting information out of you if they could.
The same standard is with Kidnappers and Child Rapists.
I'm gonna be honest, is it an Invasion of Privacy? Fuck yes it is. But what isn't these days? You can't honestly sit there and tell me our Government isn't watching us with secret eyes. Dude, they're fucking watching you now. So yeah, its not like our privacy hasn't already been invaded.
Would this be broadcast all over the news and world? Yes. But what happened when they introduced the Sex Offender's list to a public nation? It has actually decreased that of child rapists. Not a lot, but some.
If the world were to introduce a chip like this, ignoring the invasion of privacy, it'd actually send a solid message to anyone thinking of kidnapping a child. They'd have to learn where this chip would be. And on that note, not every chip has to be in the same place. Get it out quickly, and do whatever it was they were going to do originally. Thats a lot of work, just to attempt raping a child.. and I honestly believe most rapists would just give up - instead of trying harder.
On the flip side of this, if you don't think about this type of device.. then we're no better off than we are now. So in retrospect, what harm would it do?
I seriously think if a killer is going to cut open a person to get a chip out.. well, yes its cruel and yes its going to be painful - but once again, you're just magically forgetting that if you get kidnapped or taken by someone like that, you're practically as good as dead to begin with. At least a chip like this, could help lead to finding the guy/girl who tried/did kill their victim, a lot quicker.
