That is not true. A crime scene investigation may involve theories that require supporting evidence but that evidence is not necessarily a conspiracy in the legal sense. In order to be a conspiracy, more than one person needs to be involved in the commission of the crime.
“In order to be a conspiracy, more than one person needs to be involved in the commission of the crime.”
That is how it supposed to be... But if the suspect is not alone and has any associates at all with them it is always a conspiracy until evidence to the contrary is realized. Everyone present is automatically guilty until they prove their innocence.
Please do not say that this is not true. I have personally been through this “cop mind” reality far too many times.
