Does it work?

Yes Dispatching More police  to areas  like Encanto, Mary-vale and many more places has had a decrease in crime/violence when more police were added. 

What are the advantages and disadvantages ?

The advantages are:

• Less violence/ Discouraging crime

• Boosting peoples confidence in the safety of their communities 

• Saves lives

• Public safety

The disadvantages are:

• A negative reaction from the people

• Police  violence  and further erosion  of the public's trust

• Unfavorable attitudes towards the Law enforcement 

• Aggressive responses to minor offenses 

If we were to do this we would need the government's approval  to add more police to the streets. This is constitutional also because this would not violate the peoples rights.
