I think the officer violated the 4th Amendment and should have had a warrant for his actions to be legal. I think that the officer did not provide solid proof or evidence that led him to believe the suspect was a drug dealer he took illegal action to obtain information.
2, Assuming a warrant is required, what practical problems may officers face in similar cases based on what you have learned about proper procedure for executing search warrants?
I think that officers will face more problems when they lack probable cause. In this case the officer went on a hunch without seeing, having any witnesses or hearing of anything that could possibly lead to obtaining a warrant. This seems to be an ongoing issue for officers because they’re many people that can be read about that feel they have been a wrongfully abused or a subject of officer misconduct.
