They're ideal soft targets. Not only would it be useful for these Islamic terror orgs to instill fear, it would also pull at heart strings even more to find out defenseless animals have been hurt or destroyed, or, let out on the loose.

Could any of you imagine seeing a bunch of predators let loose in Manhattan, Miami, San Diego, Houston, Dallas, etc? Imagine being in Central Park having a picnic, when all of a sudden you see a fully grown male lion walking toward you, while his pride is behind him stalking some old lady's designer poodle mix. Or, you're at some park in Coral Gables and all of a sudden you hear an explosion and gun fire. A few minutes later, a troupe of macaques and baboons goes running by after escaping the Monkey Jungle. Later, on the 6 p.m. evening news, it's reported that 6 people wearing burkhas and s-vests clack themselves off, killing and wounding dozens of people and monkeys and allowing dozens more to escape.

That would be in the news cycle for days, if not weeks.
