Build a secret compartment, go to jail

KindMind writes: Alfred Anaya was a custom stereo installer who branched out to making secret compartments for valuables, who the DEA sent to prison as a co-conspirator when a drug dealer used his creation to smuggle drugs.

But Wired points out the bigger question: 'The challenge for anyone who creates technology is to guess when they should turn their back on paying customers. Take a manufacturer of robot kits for hobbyists. If someone uses those robots to patrol a smuggling route or help protect a meth lab, how will prosecutors determine whether the company acted criminally?'
