> modifications or misuse by an operator could nevertheless turn the ADS into a more damaging weapon which could potentially violate international conventions on warfare

Safe? When manned by actors known to shoot journalists in the head with “less lethal” weapons?

Some passages from your source:

ADS operators would be exposed to more than the standard maximum permissible exposure (MPE) limits for RF energy, and military use requires an exception to these exposure limits

According to Wired, the ADS has been rejected for fielding in Iraq due to Pentagon fears that it would be regarded as an instrument of torture

Seems to have problems on both ends.
