If they want them they will get them and the kids near me DO carry tools.
When my silver ones went missing off my 182 I stopped at bunch of kids with bikes with nice dust caps on and asked them if they knew who took them, they immediately pointed out the kid that done it who said he had sold them but offered to steal me some more in 10 minutes LOL.
I asked them about the theft proof dust caps and if they were worth it... One pulled out pliers and another pulled out a screwdriver and said "Dead easy, that's why we've got these"
