Basically in my story, the police are following one of the suspects of a criminal organization. They survey him from far away, as the suspect drives on the highway, out to a secluded spot of land. The suspect, digs up some things out of the ground, that he needed at the time, reburies the dug up hole and leaves. After he leaves, the police go to see what is buried, and they find evidence videos of blood ins that the leader of the gang was using as blackmail, in case his gang members turn on him. A blood in, is when you have to spill the blood of another person as a test, to be accepted by the gang. But this leader character video recorded them all, for leverage on his members. The police, having found the videos in the ground, were able to clearly identify the blood in victims. The leader made them easy to identify as intentional, in case any of his members turned on him. So the police now have evidence against the suspect who dug into the same part of the ground, where his stash is kept, but they also have evidence on other members of the blood ins. However, the police do not know their names, they just have faces of the killers to match with their identified victims. The police then keep on surveying the suspect and he meets up with other suspects from the recordings not too long after, the police have viewed them. The police surveying the place, that the gang is in, recognizes the faces from the videos, as those people meet up and go into the same residence. However, in my situation, the police do not a warrant yet, and do not have time to get one before all the people are going to leave the residence. In my research, I read that this evidence would be enough for probable cause, and the police can arrest them based on that, and then apply for a warrant after. However, if they were to arrest them based on probable cause, would they have to wait for the gang members to come out and start leaving the residence, and then arrest them outside? Or can the police just break into the police and announce that they are the police, and that they are under arrest based on that probable cause? Either way works for my story, I am just wondering how the police would go about it in this case.
