Should Houston Have Ordered an Evacuation?

Some people are questioning why a general evacuation order was not given for areas that were forecast to be in harm's way from Hurricane Harvey. It is easy to say "evacuate," but then executing an evacuation is not easy in any form of the word. 

There have been tragedies during evacuations, see 24 nursing home evacuees die in bus fire, which happened there in Houston back in 2005. Those are relatively fresh memories for those still in authority there in Texas.

The other issue is, "Do you believe the weather forecast?" There have been plenty of storms that took a different path or petered out before making landfall. Then, authorities are challenged for taking the wrong step in ordering an evacuation. Crying wolf is a charge that is lobbed when nothing materializes. 

For me, evacuation is like issuing a warning. I'd rather be "shot" for doing something, rather than accused and pilloried for having done nothing, recognizing that either way there are risks involved.
