Answer:
Situational crime prevention speaks to opportunities for crime.
It comprises “opportunity-reducing measures" that
(1) are directed at highly specific forms of crime,
(2) involve the management, design and manipulation of the immediate environment in as systematic and permanent a way as possible,
(3) make crime more difficult and risky, or less rewarding and excusable as judged by a wide range of offenders.
Situational crime preventions's greatest criticism posits that an excercebation of attitude may occur when a criminal changes the location of crime because the current location no longer provides opportunities for crime.
Put differently the critics are simply saying that
"If opportunities for certain kinds of crime are blocked, offenders simply resort to more violence or shift their energies to completely different less traceable kinds of crime"
