I've read the dialogue between you and your previous expert, and I'm not going to rehash all of fthat. He's perfectly correct, but I think you may understand if it's put to you a bit differently.
Police need very little evidence to get an arrest. All they need is a reasonable belief that you may have been interested
in engaging in criminal
activity. Just that little bit, and the evidence that establishes it, gives the police probable cause
to arrest, and gives a prosecutor probable cause to file charges against you.
It is very, very easy to get arrested. The evidentiary standard is just that low. BUT it is very difficult for the state to get a conviction. A prosecutor is up against the heaviest burden in all law. He or she must prove each element of the crime with which you are charged beyond a reasonable doubt.
Nobody can second guess the mind of a jury. So yes, the evidence above may lead to a conviction. It may also lead to an acquittal. It will all come down to how the facts play out in front of a jury, and whether your lawyer,through a vigorous cross-examination of the officers can create doubt about what it was that you were really up to.
