When it comes to the charges that the Police lay, it depends on what they and the prosecutor think will stick.
You dont always get charged for everything you can be charged for, but in some cases you will be loaded up, and then lots dropped when it comes to court.
It is really up to the prosecutor with what he or she thinks will make it over the line.
Some smaller charges might be dropped either because of co operation or they will make no real difference to the penalty the defendant will get.
You need to account for the fact that most charges are ended with a deal rather than going to trial. In America it is 97% by deal. A lawyer I was talking to during my compensation deal told me the figures here a re much the same.
So. Some charges may have been dropped.
But it makes the person no less guilty.
