If law enforcement had access to all of your social media, e-mails and live video feeds from inside your house then they would be able to catch criminals more effectively.
This isn't the same because law enforcement don't have access to all of your social media already. This is more like if they did but were only allowed to arrest you for you posting a video of you murdering someone, but not for you posting a video of you raping someone.
Protection against unreasonable search is written into the constitution, after all
Your car registration being checked to see who it is registered to and if you have any outstanding warrants etc is not an "unreasonable search".
This argument is such a stupid one that is purely made to pull at people's heart strings. If someone commits murder should they not be sent to jail because doing so would "separate them from their family"?
People in the country illegally should be removed from the country. Full stop. They're just deported back to their country of citizenship, unless they're one of the gang members in which case they are going to prison.
