@lupyuen It's rather odd that attempts are continually made to make weapon systems like these. A Threat Detection System integrated into an optic could have a more positive effect.

Assuming that both technologies would be used by police, the latter could prevent tragedies. The problem with the biometric systems is that they can't be relied upon. A flimsy laptop is consumer grade but military and police use Toughbooks.

It's really interesting news for Embedded Systems but certain smartphones have similar systems that have proven to be unreliable or easily defeated.

To be fair, it is rather cool to see. A violent force being exerted on electronics and the connectors could lead to more reliable connector designs and more reliable electronics. I can't think of a better proving ground than this.
