No . How do u investigate a crime without investigating the person?
Are you serious? Or just joking?
You investigate the crime....and part of that is absolutely investigate the people
surrounding that CRIME.
You do not, however, use that crime to being a lifelong investigation into that persons life an all aspects of it.
THAT is investigating the person and not the crime.
HUGE difference.
Let's say - someone is accused of shoplifting.
The justice system does not therefore have the right to look into that persons business practices, start investigating the lives of everyone around them. Begin investigating their family to look for other crimes...hoping to find something, anything.
That is investigating the person, and not the crime.
