First of all, to the first question, clearly, transit systems across the country have taken many of these measures. I think probably the one that's the most common right now is the installation of surveillance cameras. They are a deterrent to some extent, and they certainly also provide evidence in the case of incidents that can be consulted after the fact.
Protective shields have been less popular. Some systems have put them in universally across their fleets, and the chief is quite right. They're controversial in terms of the willingness of operators to use them, given the interaction they have in the customer service part of their job. The third part, of course, is the importance of training, in providing the operators with skills in defusing situations and avoiding situations and working around that.
Those are three key deterrents, three key elements that have been used quite significantly across the country and across the industry, but they're not enough.
That's in answer to your first question.
The second one is, we have an excellent network across the country. There are 120 transit systems that are members of CUTA that we can work with in terms of communications and equipping them with the tools to use locally as well as in communicating the impact of this, if the bill is passed.
