Curfew?
Bait near by, tranquillise when eating?
Use brain cells?
Explanation for BigWave:The cops go round with megaphones telling people to stay in doors in the area the animals escaped.
They place meat, cows, sheep, other suitable food (bait) around the area the animals escaped.
Then they have cops/game wardens with tranquilliser guns in cars waiting for the extremely precious animals.
And trucks with suitable cages.
It was a shameful turkey shoot, I don't care who thinks it was justified. The animals hadn't ventured far from the zoo.
