Blackwater gives you gas

In 2005, Blackwater contractors dropped teargas cannisters to clear a checkpoint of a snarl of people and cars. Armchair Generalist provides some important extra information that the NY Times article lacks. (Like knowing that CS and tear gas are the same thing.)

Using CS to clear a traffic jam, of all things, is definitely reckless, unjustified, and inhumane. Equally  frightening is imagining some panicked contractors tossing tear gas into the middle of a Ramadi intersection, where  Iraqis and Americans are involved in a confrontation.
