I'm not sure exactly what this law does, but I would like to do with a computer anything I could theoretically and legally do with my mind.

Eg. If I'm a shopkeeper and see some customer coming in who stole stuff from the shop last time, I am within my rights to tell them to leave the shop.

However if I use a computer to do the same, many countries would disallow facial recognition, keeping databases of customers without consent, etc.
