Crimes only happen if LEOs see them.
Where is the line of demarcation for LEO's to have to witness a crime? I'm sure they don't have to witness a murder to prosecute it.
There are two different things to consider. One is what action the officer may take immediately while the other is what action he may take later.
The link that was posted shows when an officer may arrest for a crime. The important part to note is that may does not equal shall. All arrests in Texas except for one (violation of a protective order) are discretionary for police. They may arrest for crimes committed in their presence or view. Note that this does not mean they need to see the crime, as they can detect it some other way. An officer may arrest if he hears a shot or if a crime occurs behind his back, for example.
So, what a police officer may do immediately is arrest in some cases and only in those cases. But there is nothing that stops an officer from investigating any crime, recovering the evidence, and filing a charge later on. Then, when the DA takes the case to a judge (well, the officer can do so also but usually the DA does it) or grand jury, a warrant is issued if there is enough evidence. Any police officer may then go arrest the suspect based on the warrant (with the appropriate restrictions for arresting with a warrant). This is how most murders get solved, as well as those cold cases we all read about. You know what I mean, cases that may be 20 or 30 years old. An officer can always collect evidence and file charges in case of real crimes.
