LOL thats how I spent my teenage years... growing up in a beach tourist town can get boring after your morning surf.
Also apparently this guys ex told the cops a few years ago he was unstable and making bombs, cops knocked on his door, he didn't answer so they just forwarded the info to the FBI...FBI dropped the ball as usual..
Police/FBI/whoever need to have a search warrant in order to be able to go into someone's private property. They need to have grounds (evidence) sufficient to justify that search warrant, or to justify entry without warrant in the case of an emergency - and there had better be an actual emergency in order to do that without getting in a whole lot of trouble. It has to be this way, unless you want a society where the police can search your property and belongings at any time they want without justification. "Because someone said so" generally isn't sufficient justification for a warrant. Ex boyfriends and girlfriends say all sorts of things all the time ... doesn't mean such accusations are true.
If they never found enough evidence to justify that search warrant, they wouldn't have been able to pursue it.
Means the guy was good at covering his tracks.
