Answer:
The 4th amendment gave citizens basic legal rights, like needing a warant to search someone's home, and probable cause to conduct the search in the first place. This will most likely become more and more relevant in the coming years because of the hightened tension between African Americans and police officers, which will mean the police will be held on a tighter leash and will be much more cautious when conducting search warrants and arrests. Many, many court cases will be held against police, arguing the police had no probable cause, or they violated a citizens rights, which will be treated more seriously than in the past. (granted this is an opinion)
hope this helps! :)
