LV did not blunder

The question has been raised that LV might have blundered when he 
ordered that the dementors left the prison and the Death Eaters 
escape, I believe that it was not a mistake.

1)	We do not know that the dementors are the only guards at the 
prison.  There could be an auror base there as well.  The dementors 
are blind and would probably be unaware that Sirius had escaped (if 
they could not drain padfood, then why did they not sound the alert 
then?), therefore it might well have been someone else who rasied the 
alarm about Sirus's escape.  

2)	Continuing this thread, we know of no auror who went bad and 
joined LV.  On the other hand, we know that Dumbledore had at least 
seven aurors on his side, the Potters, Longbottoms, Tonks, Moody and 
perhaps Sirus.  Therefore, a base at the prison would be exposed to 
possible discovery by aurors, who might be part of the OOP.  

3)	The dementors do have a rather bad effect on people near 
them.  The Death Eaters might well have been in no state for a fight 
or be of any use whatsoever, until they had time to recover.  
Therefore, removing them from the prison was important.

4)	Continuing that point, leaving the dementors in an empty 
prison would serve as a red flag that they could no longer be 
trusted.  Therefore, they had to leave at the same time.

5)	Finally, the Death Eaters captured at the ministry may well 
have been ones that were untrustworthy and therefore disposable.
