Last season, these five rookies hit the streets for the first time with their training officers watching their every move. Now, the training wheels are off; they’re more experienced and ready to kick some serious butt. But they are also realizing that when it comes to getting good at this job, there are no shortcuts. And when you’re a rookie officer, a little knowledge is a dangerous thing. In their first seven months as first responders walking the proverbial beat, they’ve learned how to be cops. They’ve talked people down, kicked in doors, driven fast, shot guns, kept people safe and saved each other in the process. They’ve experienced a learning curve that’s steeper than they ever imagined, and they’ve learned first-hand that a rookie mistake could cost them their life – or someone else’s. In their next seven months on the job they’ll do it again, only… better.
