- Investigator / FIS role
- How many requests do you think you have made in the last 5 years?
- Of those cases where DNA was collected, what percent of the time was it critical to charge approval?
- What percent of the time was it useful (understanding the multiplicity of other factors).
- Is there any one type of offence where DNA evidence is considered critical to lay a charge?
- From your experience, has there ever been a case where there was confirmed DNA evidence, and crown did not approve a charge?
- From your experience, what is the level of receptivity of Crown?
- Why do you think this?
- Have you seen any improvements over the years, or does it appear to be the same (process, timely results, and assist with charge approval?
- From your perspective, is there a shared attitude towards any part of the lab request process, or functionality of the national Data Bank?
- If you could be in "charge" for a day, and could change any part of the process (from beginning to end) what would it be and why?
