Warring monkey gangs? Like the Jets and the Sharks?
"Familiarity with firearms"?!?
I hope that just means that the macaques recognize the tranquilizer guns the cops are using and flee before they can get darted. Because the other possible interpretation is... well, we've all seen that movie and it doesn't end well.
Wait, we have the org charts for the gangs?
Clearly, there's only one solution to this problem: We have to get a monkey boy from one gang and a monkey girl from the other to meet and fall in love...
"Two troupes, both alike in dignity,
In fair Lopburi, where we lay our scene,
From ancient grudge break to new mutiny,
Where monkey blood makes monkey paws unclean.
From forth the fatal loins of these two foes
A pair of star-cross'd lovers take their life;
Whose misadventured piteous overthrows
Do with their death bury their parents' strife."
