I still say 67 years of no tigers getting out and attacking zoogoers - then this incident = something really bad was done to provoke the tiger that had never been done before.
... And for 50 years of no one got through airport securtity with a weapon that could bring down a 747. Therefore we must have have very good airport security on 9/11. [/sarc]
The point is that the zoo’s walls were below recommendations and below the height that the zoo stated in its safety records. We know the wall was too low because the cat got out.
