1. Do the Dyfed-Powys Police use tape lifting as part of forensic particle evidence investigations? If so, what tape is used.
2. Do the Dyfed-Powys Police use optical (compound) microscopy as part of forensic particle evidence investigations?
3. Do the Dyfed-Powys Police use a database of particles and or particle characteristics within your forensic particle analysis work, if so, what databases do the Dyfed-Powys Police use?
4. Do the Dyfed-Powys Police maintain a reference collection of particles for comparison within the forensic trace analysis work, if so, how many specimens are maintained approximately (ball-park) and who created them (again very general information would be very welcome).
5. In the event that neither a database or reference collection are contained, then how is a definitive particle identity confirmed.
