what a waste! or policy before trust?

ok, so i had the morning off today...
and when i got to my mac mini to check my mail i noticed that yet another has added me to their list of people to follow on twitter.
@milblogging or 'Military Blogs'
how intriguing i thought, as non of my interests or comments had anything to do that would even come close to anything 'military'.
well, i am aware a high number of twitters follow just about anyone - promotion - yes?
and having seen an add to interest people in becoming reservists in the RAF here in the UK, i thought, ok somebody is becoming desperate.
anyway, refusing to judge a book by its cover i thought, well then lets check the profile.
i ended up reading the blog entry on @milblogging's site.
here: Troops destroy beer in Iraq.
the entry displays a truck crushing beer cans left behind at the foreign compound, now occupied by the US Troop.
well, i get the policy about alcohol in a combat zone, but destruction?
why not give it to civilians?
or how about keeping it save until 'the fighting's over'?
i understand they should not consume alcohol, but i can't quite get the 'possess' part of the policy. Seems to me like lack of 'trust'.
making sure the beer is destroyed to even avoid temptation?
don't soldiers have the discipline and strength to withstand that kind of temptation?
i think its a question of trust, at the expense of good beer going to waste.
it just shows that policy has no room for faith, trust or consideration for the healthy level of common sense and understanding a good soldier should naturally possess...
personally i don't support fighting as a solution for any issues or differences,
but i understand a soldier has to do a job like we all have to, and as long as politics endorse conflict, somebody has to do the job to deal with the consequences.
but if even set policies seem to discount respect and belief in the people they are intended to protect and guide, than - to me - the whole idea of 'combat to protect all' doesn't seem right.
it is a job nevertheless and i respect anyone simply doing their job.
there is a compromise in everything we do - every day.
and we all have choices.
it would be a perfect world if we all would always choose the right thing to do, but in reality this world is simply not perfect, and we all learn at one point or another to deal with it.
thank you...
