I got some questions about this context. 1 What does "This just in" mean? 2 Why the author use "shooting, jumping, threatening and driving" here? is that because of certain tense? 3 Why the author use "driving away at speed" not "at a high speed"? This just in: Four men have been arrested in the robbery of the First Premium Bank on Fourth Street, which happened just this afternoon. The men did not wear masks, and they were caught on video camera, shooting their guns into the ceiling of the bank, jumping over the counters and threatening the staff. The staff immediately lay down on the floor. The gang was then seen throwing bags of money into the back of a van, jumping into the van and driving away at speed. They were caught on Highway 12, driving over the speed limit, by a traffic police officer. Thanks for your answering !
