Read the Supreme Court's decision inTerry v. Ohio (1968.)https://www.archives.gov/founding-docs/constitution/what-does-it-say

An officer on routine patrol is dispatched to a location for a noise complaint.Upon arrival the officer sees the Defendant open the door and screen, but when the Defendant sees the officer, he quickly slamsthe screen door shut, leaving the front door open.The officer presses his face to the screen and sees what he believes to be syringes on a table in the hallway.The officer then goes around the property, opens the back gate and sees the defendant standing over the toilet trying to flush something in a ziplock baggie.The officer then enters through the unlocked back door and arrests the defendant and the other two occupants of the house.

What issues regarding applicability of the 4th Amendment may be raised at a subsequent trial? Do you think the evidence seized should be admissible against the defendant? Why or why not?
