Their are two sides of the coin on this.

I for one would never want to leave my pets behind
in any type of disaster.
I would probably get arrested for forcing my way
through those lines too.)

But on the other side of the coin.
By going back into the danger zone you not
only put yourself at risk but the peace officers and
other emergency workers lives too.

Many times emergency workers have to put them
selves in the line of danger to try to save the person
who has made a choice to stay behind or sneak
through those police lines.

Just a thought.
