gifted asked same not long ago, and gd smacked him with the rolled newspaper. thought the lesson were driven home. silly o' us.
regardless, you are gonna need be specific. who is "everyone" and what specific issue are you speaking 'bout? regardless o' legality o' presence in the USA, all human beings is afforded a few basic rights by the US Constitution. one reason why a number o' administrations, democrat and republican, kept guantanamo viable as a detention facility is 'cause it were arguable not in the US. non-citizens who were held outside o' the US were having less/no rights, or so the argument were presented. but step foot in US and those Constitutional protections would immediate kick in and take effect, protecting due process rights and other such defenses. so an immigrant who manages to make it to the US, legal or otherwise, gots basic rights. am not certain why folks convenient forget that fact.
also, as hurl points out, the immigrants is being held for civil offenses. is on par with minor traffic violations. hit and run and reckless driving is criminal, but minor traffic infractions is civil... and so too is illegal border crossing. so akin to parking or speeding ticket... but no more than 10 mph over the speed limit as that often is the point when excess o' speed triggers reckless.
'course even the most hardcore natavits who has at least a couple firing neurons would balk at making border violations criminal. why? 'cause then you gotta give accused illegal immigrants criminal trial protection such a speedy trial and lawyer and jury. at the moment, you got thousand and thousands o' backlogged cases-- years o' backlog. toddlers is being ushered into immigration courts where judges s'posed explain to the child their rights and responsibilities.
this ain't a joke, and it happens daily... many times a day.
am thinking far too many people have no idea what "illegal immigrant" means insofar as legal rights is concerned, or they is convenient forgetting.
maybe you don't like the Constitution? you are welcome to try and change it.
HA! Good Fun!
