“The technically savvy are on notice that they must be very careful about whom they deal with, since calculated ignorance of illegal activity is not an acceptable excuse. But at what point does a failure to be nosy edge into criminal conduct? The challenge for anyone who creates technology is to guess when, exactly, they should turn their back on paying customers. Take, for example, a manufacturer of robot kits for hobbyists. If someone uses those robots to patrol a smuggling route or help protect a meth lab so that traffickers can better evade law enforcement, how will prosecutors determine whether the company acted criminally?”
