Is it a good idea to make all law enforcement policy public?  I'm specifically referring to the internal logistical details of law enforcement policy.  

Are you saying that there is never a reason to keep internal procedural policies confidential?  Do you think the USA would still be around today if our government agencies disclosed everything to the public? 

Are there abuses?  YES!  Unfortunately that's the catch 22 of holding power.  
On a national scope, you have a "vision of the USA" being much better, but like every other naive idealist, you fail to consider the kinds of threats that have been extinguished because law enforcement agencies have been able to maintain confidentiality regarding internal policy.  

I'm skeptical of those who have strong opinions and aren't privy to the information necessary to allow them to develop informed opinions.  Frankly, I'm disappointed in the quality of comments on CB in general - seems like a majority are as idealistic as they are ignorant.
