You need a court order because the police are not the final say in obtaining personal records. Do you really want the police to have the authority to request records such as these?
If they have definitive proof that a law was broken, again, I’m not sure how getting this information is any different then entering a house where a known killer is. I’m pretty sure they do not need a warrant to follow a murderer into a house, why would they need a warrant to follow a person that broke some other law to their phone number?
Again, given that in both cases evidence of the crime existed.
I do not believe that police should be able to simply get these records in cases where they are simply investigating without a warrant, but once they have clear proof that the law was broken they are no longer investigating they are looking for the person to apply charges.

You need a warrant for searches. If I know you robbed a bank, say I caught you exiting the bank with the gun, the money and a notarized statement from you saying that you robbed the bank. I still need a warrant to go into your house to collect more evidence.
Many times for things like phone records the thing you need is a subpoena, not a warrant. You may need to have the court tell the phone company they must turn over the records to get them to do it. You aren’t doing a search, you are compelling their cooperation.
There are exceptions to warrants. Your murderer in a house, say he just killed the guy and you chased him, could fall under exigent circumstances. But a murderer who has been charged and has not been released on bail or such will have an arrest warrant. And if you have a warrant I guess you’re going to come in.
This. The cops can’t just show up at the phone company waving a gun and yelling “A crime has been committed. Give me them records!”. The phone company needs the warrant. The warrant contains the specifics of their required compliance, and that’s all you are going to get.
Warning: This was how it worked before NSA got separate, private access to all this data. Now they just take the records in a way that is completely transparent to phone company personnel, and we all just hope and pray that due process was actually followed. In other words, they aren’t showing the phone company squat anymore.
