Dangerous for Who?

Somewhat disturbing news from Zanesville, Ohio USA where a Farm owner apparently released 'his' collection of around 48 'dangerous' animals shortly before shooting himself(http://www.guardian.co.uk/world/2011/oct/19/ohio-dangerous-animals-breakout?INTCMP=SRCH). Rather predictably, the lions, tigers, bears, wolves etc also ended up  being shot by the local police force (last I heard was that one 'monkey' was still 'on the run') who took the view that doing any less was imperilling the public. It is difficult to guess at the motivation of the Farm owner but it is rather sad that many endangered animals ended up being slaughtered for no good reason. Perhaps the Ohio laws on keeping exotic species need strengthening?
