wake-up call

Joe Freeman, Amnesty International's Myanmar researcher, said the attack "should serve as a gruesome wake-up call that civilians in Myanmar need urgent protection".

Even though the fire died down and officials said there were no injuries and little damage to speak of, some residents said Thursday was a wake-up call.

“This shooting must serve as a wake-up call to the far-left that their rhetoric about ICE has consequences…The violence and dehumanization of these men and women who are simply enforcing the law must stop.”

Liverpool's players were subjected to fireworks let off outside their Istanbul hotel designed to disturb their sleep - but it is a second successive loss that must act as the real wake-up call.

Homeland Security Secretary Kristi Noem likewise described the Dallas attack as “a wake-up call to the far left,” while Senator Ted Cruz demanded politicians to stop “demonizing” ICE and Customs and Border Protection personnel.
