People with malignant intentions will happily go through the painful process of obtaining an ASIC if it allows them unfettered access to carry out whatever it is they intend doing.
Forging an ASIC well enough to get past some guy with a big belt and trousers tucked into his boots at a gate surely can’t be all that difficult.
Please don’t make the mistake of believing that an ASIC is a silver bullet to save us from terrorists. At best, it’s an easily overcome inconvenience to them.
