- interpersonal coherence - way offender behaves at scene may reflect their beh in everyday situations
- some rapists may be more apologetic and others more humiliating - may reveal how offender behaves around women in real life
- Time and place is also significant, as is forensic awareness - people who have been investigated before - know how to cover their tracks
- Geographical profiling
- Assesses location of linked crime scenes - likely home or operational base - crime mapping
- Can be used to help with knowing what offender is thinking - as well as their modus operandi
- Offenders like to work in areas they are familiar with so shows a centre of gravity and may also help police with where the next strike is - jeopardy surface

- Can be used on more than just **** and murder as geog profiling can help show base of thieves too
- increases usefulness

- does not always lead to correct identification
- information from profile only led to correct identification in 3% of cases but was useful 83% of the time
