There are many Mudcat members who see nothing wrong with the use of drones by police and other such authorities. Their reasoning is that if you have nothing to hide then why worry. They frequently use the term tinfoil hat.

As for which governments have condemned or voiced reservations about the use of drones to kill people, a quick Google found the following:

'EU Parliament proposes a ban refers drone strikes as "unlawful."

Strasbourg - European Union Members of Parliament condemned the use of drones in targeted killings in a vote of 534 to 49. The vote proposing a ban referred to the drone strikes as "unlawful."'
