There might be a little more to it then 2 guys not getting along.

might be more to it...

coconuts trees were cut down, 2 men arguing, police were called. arguing continued, argument broken up

not much later a fence going up on the soccer pitch.

Reaper says all is well with the Skydiving event so not to worry.

Well it is private property - seems that the owner is establishing his boundaries and taking steps to prevent trespassing.

Hope this calms down and nobody gets hurt.

I know of a landowner in England who erected a barbed wire fence alongside a bridleway. After a horse was injured he was ordered to take it down. He didn't and was subsequently heavily fined.

No-one has the right to erect a fence that is likely to injure legitimate travellers. If he wants a barbed wire fence it must be well into his property with clear indication as to where the actual legal border lies.

I am not a fan of barbed wire and agree there would have to be a lot of "flags" marking the wire so people don't get hurt.

It is guaranteed that someone on a bike in the night will get hurt.
Definetly needs flagging

I agree, but do you think someone could see a flag when it's dark?

What does Belizian law say about erecting a fence and type of fence to protect ones property and the responsibility to the general public's safety? I think that is what is relevant here.
