No. Everyone on 270 pulling over simultaneously for 1 car would be absurd.
I would just expect them (not that they all do) to act like they aren't in the job for gUnz n b00biez!!1!11!!!!
Common human decency says if you can help someone then help them. It just so happens that while those people on 270 may be heading to work, the hospital, etc. and may not "have time" an officer is on the job, getting paid, and should lend a hand if able. To sit and watch someone struggle is disrespectful.
That being said I personally have nothing wrong with our men and women in law enforcement. I just think that if able, they/we should help.
...and yes, before you throw the hypocrite flag I have helped/given rides to ppl I don't know when desperate, bought people meals and even nights in hotel rooms, and I have also been "too busy" to help someone. I'm not perfect. The difference is I don't get paid and didn't take an oath "to protect and serve."
Just MHO.
