In People v. Arias, 179 Ill. App. 3d 890, 895, 128 Ill. Dec. 875, 535 N.E.2d 89 (1989), the court found that the police did not violate a suspect's fourth amendment rights when they entered the exterior door of a front porch to knock on the front door of the residence to make an arrest. Similarly, in People v. Greene, the police investigated a 911 hang-up call at defendant's residence. The police officers first knocked on the screen door of defendant's porch area and, after receiving no response, peacefully entered the porch area to knock on the inner door. People v. Greene, 289 Ill. App. 3d 796, 802-03, 224 Ill. Dec. 793, 682 N.E.2d 354 (1997). The appellate court found that the officers did not violate defendant's fourth amendment rights because "the officers were justified in making a peaceful entry onto the porch for the purpose of attempting to raise the occupant of the house." Greene, 289 Ill. App. 3d at 803.
