the black jackets for beginners

The "Black Jackets" are a Muslim gang currently operating in Dublin.
The gang has been extending its power throughout the city over the past five years.
Ordinary Irish people are now accustomed to being harassed by members of this gang on Grafton Street, O'Connell Street, Abbey Street and other city centre locations.
A member of the gang works as a security man in the McDonalds fast food outlet on Grafton Street.
Another works on security at the Stephens Green/College of Surgeons carpark.
(Infiltrating security companies has given the gang the capacity to insert itself into a number of businesses and organisations which otherwise would have been difficult to penetrate.)
A member of the gang works as a sign holder for Timberland, often standing on Grafton Street or Dawson Street.
(Working as sign holders allows the gang to carry out monitoring and other activities on the streets without fear of being moved on for loitering.)
Several gang members are on the staff at the Kylemore cafe on O'Connell Street and in the Kylemore foodcourt in the Stephens Green Centre.
The gang meets on a daily basis at the front tables in the Kylemore Cafe on O'Connell Street.
Kylemore Cafe security staff turn a blind eye to harassment activities carried out in the cafe.
The Black Jackets gang is multi ethnic.
Its composition is essentially Arab and Pakistani but it also includes Malaysian, Indonesian and Indian (Hindu) Muslims.
My information is that the gang has associations with Nigerian groups based in Dublin.
The Black Jackets is a street gang whose unifying ethos is Islam.
It is hiding in plain sight in the city of Dublin.
