"An Garda Síochána is determined to protect communities from the potentially devastating impact of these drugs and firearms"
The senior officer said the operation had been "highly targeted" and had involved "close co-operation" with the Police Service of Northern Ireland.
Based on my perception, the word communities has to do with small groups in a society, such as youngsters at schools or on the streets, or even could refer to street kids. Highly targeted has to with targeting the most important figures in charge of an event. And in the last one, although I know the meaning of cooperation, I cannot understand why the writer has written it in a way as if it is an adjective!
