Lazs have you seen the metalstorm pistol? Its chipped. I thought that would be a good idea - i'd stop anybody from using your gun against you... don't you think?
The state of New Jersey passed a gun control law which states that as soon as the first gun that has technology like this has been on the market for 6 months in the United States, only pistols with this technology can be sold in that state.
This law has an exemption for the police because as we all know, chip based technology fails at the worst possible moments. The police in New Jersey specificaly refused to use the technology. So they were conceeded in this law super citizen status by fiat.
This kind of technology allows abuse by the state. It can be modified to allow your local police to have an enabling\disableing master control. The LOWJACK chip technology is easily incorporated into the owner recognition technology. At which point the police can be notified by your pistol that it is active and it's location. With the same technology the police can remotely disable your access to your pistol.
So extending this a bit farther, New Jersey is famous for passing laws that won't pass constitutional muster without its corrupt state government forcing it through against the will of its citizens. They would eventually tag on an addition to the current law something like, if your pistol does not phone(RFID/WIFI) home to the local police station from an expected storage location, at predetermined times, you have just become a criminal because your battery died.
Since no electronic technology is ever 100% and citizens in most countries have very littel oversight control on the local police. It has been my experience the police are not very motivated to oversight them selves for accidents such as the master control going on the fritz and disabling all pistols in a 10 square mile area. Or that that 50 pistols not phoneing home on time might constitute a systems failure at their end.
Only a fool hands over thier duty of personal accountability to the state or to technology for the fantasy of security. The state cannot stop evil people from acting evil or batteries from running out.
