I'll throw in my two cents from a U.S. citizen standpoint:

 

1. Nice to see the Benjamin Franklin quote reiterated because it really sheds a necessary light on what the founding fathers intended the constitution to convey.

 

2. Of course safety and security is very important, especially in the age of fears of terrorism; almost paranoid in nature IMO. Domestic terrorism is a real thing, but "stop and ID" is bullshit to me and unless being investigated for a crime, or operating a motor vehicle, I think that people should be vigilant of their rights and exercise them. Walking or going about your daily life isn't a crime and it shouldn't be treated as such. There aren't terrorists walking the streets around us that are going to be apprehended and prevented from committing acts of terrorism because of a stop and ID.

 

3. There is a right and a wrong way of going about exercising your rights. The people who proudly post themselves on youtubes "sticking it" to law enforcement and being belligerent in the name of the constitution erodes the respect that the documentand what is stands for is rightfully owed.

DUI checkpoints aren't majorly for only DUIs... They can include numerous other things. Checking to make sure the person doesn't have a warrant, or checking and making sure they can even legally drive on the roadway. Saying that it gives up their rights is just plain dumb... Okay, yeah. You're inconvenient for maybe 3-5 minutes, big deal? In other countries (Less civil rights ones) It's either a pull over, and let the MILITARY check you or take a bullet to the skull. DUI checkpoints are generally quick and simple, it's those that look to make trouble for themselves like those who put up signs saying it's illegal detainment, and they wish to not speak to an officer, etc that end up making themselves be there for hours. I'd much prefer having 3-5 minutes of my shitty day taken away, and have my "rights" taken away then be hit and killed by some drunk asshole that can't just walk home or call a cab. Sorry if you don't feel the same way but piss off either way. :P 

Now for checking IDs, that's a bit too far out of reach but I mean eh, I don't really mind. 

But saying it might stop terrorism... BRUH just no. If there was terrorism, I highly doubt they'd be like "Shit bro, we can't kill some innocent people that are defenseless because of these damn checkpoints, guess we'll turn around and do it some other time" No, they're still gonna fuck shit up so I think it'd be more of a public safety thing than a anti-terrorism. (Getting those who shouldn't be on the road, off it) 

Ya fully agree with lcso sergeant jester.. 

 

In singapore, when we are requested  for ID/IC checks by the police or any law enforcement officer we need to show them our identity card . Failing to comply and failing to provide them your ID is considered a offence by laws.  We do not have human rights compared to US. But is ok, personally I think ID checks is needed because only for a few minutes of time, you can make your country safer
