24th century United Earth France isn't exactly the same thing as 20th century real life France. United Earth would need to have a unified law system, for no other reason than the ease and speed of travel. It's likely that weapon ownership isn't heavily restricted on Earth at this time, especially since TNG era phasers are multi-purpose survival tools in addition to weapons. (And it's probable that America would insist its second amendment be integrated into the United Earth Consitution before signing on.)what law are you kidding?
murder, in france having live firearms unsecured is a crime, using them and not reporting killings and fleeing earth....yeah thats a few crimes.
Do remember that this is a civilization that lets schoolchildren play with antimatter for their science projects. In a setting where any teenager could easily make a multi-megaton bomb just from school supplies, I don't think they're worried too much about weapons control.
I am aware the romulans are to blame but the police have dead bodies and on
but you are all overlooking he left earth right after killings, the police have a pile of dead romulan bodies on a farm worked by romulan servants,
starfleet is likely to be bad it always is, and tje federation has a history of throwing people under the bus to protect a treaty
reporting something to starfleet is pointless, they are not the police and Admiral clancy is very likely to be bad very few starfleet admirals are good after all.
who said it was a home invasion? the police never watched the scene on tv.
they arrived, a pile of dead unregistered romulans are sat there presented to them by two romulan servants on a farm whontold them boss man had to defend himself.
where is house owner? bossman left earth right after the event, but it was self defence.
Now tell me if a pile of dead mexicans turning up on a us farm that used mexican workers wouldn't raise police eyebrows, now add to that the owner who had helped kill them had mysteriously left the usa right afterward without waiting for the police what would the police reaction be?
I say a murder enquiry would be launched and a warrant for the persons arrest would be issued.
When was the last time there was a murder on Earth of all places? TNG-era Earth is a crime-free utopia. The police aren't equipped to handle murders any more than modern police are equipped to handle dinosaurs. They're a thing of the distant past, and generally a waste of resources training people for.
Laris and Zhaban probably disposed of the bodies, as well. Phasers have a vaporize setting, so it's pretty trivial to do. A murder investigation would require establishing that those Romulans actually existed in the first place.
