Blowback is unintended consequences of a covert operation that are suffered by the aggressor. To the civilians suffering the blowback of covert operations, the effect typically manifests itself as "random" acts of political violence without a discernible, direct cause; because the public—in whose name the intelligence agency acted—are unaware of the effected secret attacks that provoked revenge (counter-attack) against them.
Blowback is a system of operation for self-loading firearms that obtains energy from the motion of the cartridge case as it is pushed to the rear by expanding gases created by the ignition of the propellant charge.
Several blowback systems exist within this broad principle of operation, each distinguished by the methods used to control bolt movement. In most actions that use blowback operation, the breech is not locked mechanically at the time of firing: the inertia of the bolt and recoil spring(s), relative to the weight of the bullet, delays opening of the breech until the bullet has left the barrel. A few locked breech designs use a form of blowback (example: primer actuation) to perform the unlocking function.
Other operating principles for self-loading firearms include blow forward, gas operation, recoil operation, revolver, Gatling, and chain. The blowback principle may be considered a simplified form of gas operation, since the cartridge case behaves like a piston driven by the powder gases.
Blowback is a 2000 film directed by Mark L. Lester. It follows detective Morrell (Van Peebles) as he investigates whether a series of murders, identical to those by Wittman (Remar), executed years ago, are copycat or if they could be Wittman himself. Filming took place in San Diego, California.

Blowback can also refer to the combination of gasses, dirt, and debris (unburnt powder, metal shavings) that most firearms produce upon firing. This can cause great irritation to the eyes and most ranges or organizations suggest or require the use of safety glasses when firing pistols.
Blowback is the fifth album by Tricky, released in 2001. Like Nearly God, Blowback contains several collaborations, but the album's sound is much brighter and more relaxed by comparison. Tricky himself said that he wanted to get airplay with this album, while most of his earlier albums were made to stay off the radio. Guest performers on Blowback include Flea, Anthony Kiedis, Josh Klinghoffer, and John Frusciante from Red Hot Chili Peppers, Cyndi Lauper, Alanis Morissette, Ed Kowalczyk and less known artists such as Hawkman, Stephanie McKay and Ambersunshower, with whom he already worked in 1996 for the charity compilation Childline.
A new song called "Question" and an alternate version of the song "Diss Never" (both with Alanis Morissette's vocals) are still unreleased, because her label Maverick Records held them back.
