It is difficult to express the trauma that we and our families endured over four years until the case against us was dismissed. If I had not met David and we had remained with the previous solicitors I believe that we could be serving a prison sentence now as a result of the sheer amount of mud thrown and the unfairness of the investigation. I cannot speak highly enough of David and his team. He undertook the task of defending us with the disadvantage of being at least two years behind the prosecution. The team worked tirelessly to understand and manage the heavy, complex prosecution case against a background of procrastination and a lack of openness by the police.” Client
