An adjournment is normal under the circumstances. The case will start again when the defence & prosecution solicitors have had a chance to analyse the CCTV. Your sons solicitor will then advise him as to his best option. Depending on what the CCTV shows this could be to plead guilty or to go to trial. Remember there is an automatic 1/3rd reduction of the sentence in return for a guilty plea. The police will not lie. The CCTV will be available to view in court anyway ,so lying would just harm the case. He should be told how long the Adjournment is for.
