PORT OF SPAIN, TRINIDAD AND TOBAGO — Trinidad and Tobago on Monday declared a state of emergency due to a spike in murders by criminal groups, a move that grants police the ability to conduct searches and arrests without a warrant over the next two days. “The circumstances warranting the declaration of the public emergency are based on the advice of the Trinidad and Tobago Police Service to the National Security Council of heightened criminal activity which endangers the public safety,” Prime Minister Keith Rowley’s office said in a statement. Attorney General Stuart Young said the country recorded 61 murders
