Explanation:
The barbed wire on top of fences can be tilted in or out, which also
provides extra protection. If the organization is a prison, it would have the barbed
wire on top of the fencing pointed in, which makes it harder for prisoners to climb
and escape. If the organization is a military base, the barbed wire would be tilted
out, making it harder for someone to climb over the fence and gain access to the
premises.
