, he considered that the animals would be easier to catch, examine, and release if a dose of tranquillizer could be administered by projection from afar. To that end, Murdoch went on to develop a range of rifles, darts, and pistols.
The first modern remote drug-delivery system was invented by scientists at the University of Georgia in the 1950s, and was the direct predecessor to the Cap-Chur equipment used worldwide for decades.

. The dart is propelled from the gun by compressed gas, and it is stabilized in flight by a tailpiece consisting of a tuft of fibrous material. The needle may be plain or collared, with a barb-like ring to improve retention of the needle and syringe to assure that the full dose is administered.
Methods of driving injection upon impact include: gas compression, spring compression, explosive charge, or gas evolution reaction A gas evolution reaction is a chemical reaction in which one of the end products is a gas such as oxygen or carbon dioxide. Gas evolution reactions may be carried out in a fume chamber when the gases produced are poisonous when inhaled or explosive. ...
. In one example, compressed air or butane in the rear of the dart pressurizes the solution, while the needle is capped to hold the fluid in place. Upon striking the target, the cap is pierced by the needle as it punctures the animal's skin. With the pressure released, the compressed gas pushes the solution out of the syringe and into the target (see diagrams fro

arsenals because a human can easily be wrestled to the ground, the pain induced by the dart may cause a suspect to pull out a weapon or panic and run until they are far away resulting in the officer having to track down the unconscious suspect, a human can have a deadly allergic reaction to a tranquilizer, and because effective use requires an estimate of the target's weight — too little tranquilizer will have no effect, and too much tranquilizer will result in death, which can lead to a lawsuit or being convicted of second-degree unintentional murder if the target is a human. "If you shot somebody that was small, it could kill them. If you shot somebody who was big or had drugs in their system, it might not do anything." says Newett, of the Justice Department. Harold C. Palmer said he only knew of one case of a tranquilizer dart being used against a criminal. This was in 1961 in a prison in Athens, Georgia. A 220-pound prisoner went berserk and the guard shot him with a tranquilizer dart. Six minutes later, the prisoner lost consciousness.
