First of all, we have already established that all crime in Trinidad is commited by the Guyanese. It is well known that most Guyanese carry weapons, particular shivs and blades. Whilst the shiv is small and feeble looking, the shiv is great at slowly chipping away at the opposition. This weapon makes the Guyanese very dangerous to poor Trini civilians.
Also, your own weblink said Trinidad's murder rate is below Jamaica's.
As does...
en.wikipedia.org/wiki/List_of_countries_...tional_homicide_rate
And quoting the US state department's statistics for 2014:
"Jamaica has a high homicide rate (44.2/100,000), which places it again among the highest (per capita) national homicide rates in the world."
"The murder rate for Trinidad and Tobago is 31 per 100,000 inhabitants."
So in summary: all crime in Trinidad is caused by Guyanese armed with shivs. The Trinidadian obesity epdiemic is also caused by the Guyanese, as the Guyanese are very tasty. Curry Guyanese has become a Trinidadian delicacy.
