There are 4 situations in which an arrest is permitted...what are they?

INTENT

AUTHORITY

SEIZURE OR DETENTION

THE UNDERSTANDING

Explanation:

INTENT = A Formulated design ; a resolve to do or forbear a particular

act; aim; determination. Intent shows the presence of will in the act which

consummates a crime.

AUTHORITY = State laws give police officers the authority to place

citizens under custodial arrest, or them them into custody.

SEIZURE OR DETENTION = A necessary part of an arrest is the

detention of the subject. Detention is considered to have occurred as soon

as the arrested individual submits to the control of the officer.

THE UNDERSTANDING = of the person being arrested. Through

either words - such as “you are now under arrest” or through actions

such as forcibly subdued by the police, handcuffed, and placed in a patrol

car. This understanding may be lacking if the person is intoxicated,

insane, or unconscious.  

the above answer is upto the mark by my knowledge
