Yeah, get to the walkie-talkie. Although, I think that even if this is just practice, they want you to act like it's a real crime, so don't investigate yet. If you do, I think you'll "fail" the test, cuz otherwise you'll never be able to act in a real crime, cuz you won't have experience, cuz you'll have labored under the delusion that everything was safe and planned. So don't keep the mentality that it's just practice, cuz who knows? Maybe it isn't. [if that makes sense to anyone... ]
