I wonder what law enforcement agencies would do if someone made an assassination market. Similar to SR really, Tor hidden service and all that but instead of buying drugs you place bets on the last day a person will be alive. So you can place a bet that the lead agent of the DEA for example will not be alive on a certain date. The person who picks the correct date wins the entire jackpot, payable in anonymized bitcoins of course. It shouldn't be a Tor hidden service though, NSA might attack a site like that. The most scary thing about assassinations is how anonymous they can be. Look how hard it is for them to trace drug packages it is probably no easier for them to trace bombs. Hell it took them ages to get the Unabomber and they only got him via a writeprint analysis attack done by his brother. This technique is often very frequently used by special operations teams for the assassination of targets, so they seem to think it is very effective. Don't over estimate the powers of law enforcement. They are generally a step behind. We could pwn them. However the military would pwn us. Another good idea is the use of self made UAVs. There are open source software solutions for flying them. And open source designs for making little flying helicopters even. Plus you can even buy them, but that might not be a good idea. There is really no reason why you couldn't use a laptop in one part of the country to control a mini helicopter on the other side, just use a cellular phone network and a VPN. There are mini UAVs with cool features, you can lock them onto vehicles etc and they can carry multi kilo loads. Some sophisticated smugglers use things similar to this to fly drugs over borders, but they could also be weaponized easily. Booby trapped homes that you get raided could probably wipe out SWAT teams fairly effectively.
