Lowering the speed limit on residential streets from 25 to 20 mph is totally wrong ("Bill to lower Portland speed limits heads to Gov. Kate Brown's desk," May 31). How many of the 44 people who were killed on Portland streets in 2016 were killed by vehicles going at 25 mph? Probably none. And the new law is probably illegal; cars are less efficient at the slower speed and no evidence of an environmental impact study was done.

Sure, it sounds like a good idea, but unless you can enforce the 20 mph speed limit with more police, all this really does is punish those law-abiding citizens who obey the traffic laws because it's the right thing to do. The speeders will speed no matter what number is on the speed limit sign. Catch the speeders and leave the rest of us alone.
