I agree. Jack Hanna also pointed out that since this took place at night, tranquilizing the animals was not a safe option.
It is very sad that all these animals (especially the rare tigers) had to be killed, but it is the fault of the idiot/coward who let them loose and killed himself, not the police who had to deal with the emergency he created.
Naturally these police will be the target of every PETA nutjob on the planet.
