I don’t think the law would do anything to you for shooting one, but, they would take all the stuff. Plus, they would probably look the other way while others stoned your house and such. You would probably be one of the least popular people on the planet.
You’d be pretty popular once they rifled through the alien’s stuff and found the cookbook.
This thread made the “Threadspotting” feature thingy 
what if the alien likes football?
what if the device he points is a hand held replicator and the alien plans on generating hot nachos and cheese and a keg of beer? or the device could be a 3D projector to view the game?
Yeah, I thought it was so hilarious so I took the liberty of submitting it. The title makes me giggle so much! And the mental image of E.T.'s head stuck over someone’s mantle.
Well, since ET is now on the way to the taxidermist, I’ll just snag, bag, tag (and hide) the replicator before Pete & Myra or Scully & Mulder show up asking for it.

Why do you suspect that? It would almost certainly be an ex post facto law.
What if the means are so primitive it never occured to them it was dangerous:smack:
What if they’re the retarded aliens from Signs? You know, the ones who run around naked and try to scratch people?
Disclaimer: I don’t believe E.T. life has ever visited Earth or will in my life. I don’t believe in bigfoot or the Loch Ness monster. But, since I was a kid, I thought, if I ever am confronted with any of these, I’ll do my best to kill it and get the corpse to a reputable authority. I think I was pissed off at the supposed abductees and sighters on TV who always came away with squat.
You know that chemical reaction is just window dressing. Being struck by high-velocity solid is the real issue. 
High velocity, yes. Solid, not so much. I load hollow points, because I care enough to send the very best.
Yeah, but that big hole coming out the back leaves less usable ‘meat’.
True, but it also reduces the chance of return fire. My .357 is a fine weapon, but ET may be packing something that would level a city block. Better to sacrifice a steak or two than risk a return shot, I think.
Also, due to taxidermy concerns, I won’t be going for a headshot. It would really suck to bag the first alien ever, but not be able to mount the head because I blew it off with a hollow point round. I’ll be aiming center mass, and pulling the trigger until I get a click instead of a BANG.
My greatest concern in this thread?
Shooting the ET automatically makes it non-kosher. I can’t join you all in munching on grilled xenoburgers. 
As to which – “xenoburger” only applies if the grillee is sufficiently similar to Terran mammals. Maybe the ET is an oceanic creature (ex: Mon Calamari), in which case I recommend a light lemon-teriyaki glaze, a bed of angel hair pasta, and grilling skewers. Xenoicthykebabs tonight!
I claim that the current law would be mostly inapplicable, but that wouldn’t really matter very much.
If it turned out that the aliens were peaceful and we realized it, you’d be vilified and quite possibly punished on whatever trumped up charges would stick. If they turned out to be peacful and we didn’t realize it, and so waged a war against them, you’d just be one more case of humanity defending itself.
If it turned out they weren’t peaceful, I expect that the laws and jurisdiction of Anystate would rapidly cease to be a going concern.
Well, yeah…but it’s ET’s own damn fault for landing in my yard, during a footabll game, with his gun ports open. Obviously, a peaceful alien would have closed his gun ports to prevent any such misunderstanding. Stupid ET. Now we have to fight a war until they figure out that [del]I’m Valen[/del] aliens and humans share the same souls. And that Skald the Rhymer is a Vorlon.

Have you seen Earth lately? The fact the it looks different and has resources we could use would be enough justification for many people to kill or enslave it.
I say barbecue his football hating ass (or xeno-equivalent) and call some friends for at tail-gate party.
Forget what he’s smoking. I want whatever you’re on.
His mom said he’s a naughty boy and can’t have any more.
