We all must remember that the police are civilians.
According to Wikipedia, there is a civilian version available for purchase in the US and Canada. It is the TC-21, the Tavor Carbine 21 meant for civilian and police use. It is semi-auto.
It is available in the US as civilian semi auto and should soon be available in select fire for LEO and Agency applications.
It is super compact and with a 16.5 barrel it just meets BATF minimum overall length requirements and even with an 18 in barrel it is shorter in overall length than an NFA 10 in barreled SBR AR-15, but with ballistics very comparable to a full sized 20” barrel M-16.
Tavor is very accurate and is comparable to Tier 1 AR-15/ M-4.
It's durability and reliability is on par with a Soviet Kalashnikov AKM.
The Tavor may be the best military autoloader in 5.56 available. It is arguably the best CQB assault rifle ever made while still being able to shoot accurately out to 500 yds with the long barrel. It was designed from the ground up for optical sighting devices as the primary aiming system
It would be my first choice for home defense or use for automobile self defense .
The thing just plain works
