How Do I Know if a Police Search and Seizure Was Legal and How Do I Fight That if It Was Illegal?

Well the way to know is to sit down with an attorney and discuss the facts with them. The attorney can then review your case, talk about all the facts and circumstances involved, and there may be legal issues that the attorney can see that may be able to get some evidence suppressed. Drug case, for example, maybe the officer did not do a legal search and in that case, if there's an illegal search, then the drug evidence can be suppressed. There are many other instances and other types of evidence that can be suppressed, but the most important thing is to have an attorney review your case to see if you have a good case for that type of motion to suppress.
