To lower oil prices: a modest proposal

This is sort of a recipe to lower oil prices. Some ingrediants are kinda exotic.

First, 'acquire' a group of 50 individuals comprised of:
Oil speculators (35)
OPEC leaders (10)
Oil company executives (5)

Take all 50 into a single large room. Separate into 2 groups of 25 each. Identify a group A and group B.

Line each group against opposite walls, facing the wall.

Then...

Put a bullet into the back of the head of every 5th person in group A, working from right to left

Give cell phones to group B

Put a bullet into the back of the head of every 5th remaining person in group A, working from left to right

Check oil prices. If too high

Then...

Put a bullet into the back of the head of every 5th person in group B, working from right to left

Give cell phones to group A

Repeat as necessary until oil prices moderate.
