Methodology of Crime Scene Photography

The methodology of crime scene photography is very specific involving certain practices to ensure that the scene is recorded as faithfully as possible for a jury to view in court. This negates the need for the jury to visit the scene (which may not be possible for several reasons) and provides views of the scene that is seldom described sufficiently in words.

As I have no longer got access to real crime scenes, a possible project idea would be to use the same photographic methodology to record other subjects which may be regarded as crimes.

I have a few ideas to follow up on this concept but here is my 1st.

Due to the recent paper co-published by Professor David Nutt as a result of a study in the Lancet that
'heroin, crack and crystal meth were deemed worst for individuals, with alcohol, heroin and crack cocaine worst for society, and alcohol worst overall' (http://www.bbc.co.uk/news/uk-11660210), it would seem to me that if alcohol is the worst drug, then it should either be made illegal or other drugs made legal!

The idea therefore is to record the buyers, dealers, consumption and after effects of taking this drug.
My 1st attempt at this took place at 7.30am on Sunday morning when I attempted to record the effects of the masses taking this drug the night before.

It was not a dry morning! This Sunday was also Rememberance Sunday and a parade was due to take place in front of the town hall. Due to this council cleaners were out from 8am. Having said that there was plenty of evidence of drug taking from the previous evening.

Reflection: 
In future I will check the local paper for deatils of any events due to take place in town on the morning of the shoot.
I will need to set out earlier to beat the cleaners.
I'll try Thurs morning after 'student' night on Wednesday.
The images should really have scales and numbers alongside them to indicate their status as evidence, this will be done should I progress this idea.
I may experiment with two flashes/open flash later.
