Would a patrol of Siberian tigers be a deterrent to illegals crossing the Arizona Desert?

After the SF zoo incident, I’m starting to think they could make a difference… ;p
OK, let’s change the patrol to tigers who thrive in hot settings. Now what do you all think?
Guys, Siberia is not perpetually frozen. There is a summer there, too. Also, the Arizona Desert is not always baking. There is a winter there, and it’s cold. You guys act like a tiger out of its habitat would just instantly drop dead.
