People have noticed that the way police handle protests is becoming more like the military.[9][10] Since the 1970s, police who control riots have been shooting at protesters with rubber or plastic bullets.[11] They also use tear gas, which was first made by the US army in 1919 to control riots. Using tear gas in wars is not allowed by international agreements[12] that most countries have signed, but using it in a domestic (inside of a country) situation or non-combat situation is allowed by police or the military.
Concerns have been raised about the militarization of police. Both liberal and conservative groups, such as the Cato Institute[13] and American Civil Liberties Union,[14] have criticized this practice. The Fraternal Order of Police argue that it increases officer safety and protect the public,[15] but studies have shown that militarized police units are more likely to have violent encounters with the public,[16] they are more frequently deployed to communities with large African American population, no matter the local crime rate.[17]
Many countries have a gendarmerie, which is a military force with police duties among civilians.

The Rangers found that the FBI used grenade launchers to fire two 40 mm M651 grenades. The Army considers the M651 a pyrotechnic device and that it is known to cause fires. The Army Tech Manual for the M651 warns that it can penetrate 3/4" plywood at 200 meters and "projectile may explode upon target impact". During inventory of the Waco evidence the Texas Rangers also found flashbang grenades.
