The usual stuff.

- members of opposition of the wrong kind (as defined by incumbent);

- journalists investigating the government;

(if the incumbent is brazen enough, those above can be and already are selectively targeted with paid exploits)

- political opponents of the wrong kind (aka the extrimists, which kinda overlaps with #1);

- actual enemy combatants (aka the terrorists), spys and traitors;

- organized crime of the day with unwarranted delusions of grandeur (R. Taghi, his antics and aspirations to kill the Dutch PM);

- immigrants and immigrants to be of the wrong kind and people who smuggle them;
