the rather famous quote of course has one point to it - that is those laws mentioned are ones only the poor have any interest in doing, although both rich and poor share the capability of it.
Thus the correct response is not to talk about killing, which is something both the rich and poor have an interest in doing as well as sharing capability, and are often caught doing, but rather:
The law in its majestic equality forbids rich and poor alike from insider trading, or dumping hazardous materials into downstream waters from their factories.
This, rhetorically speaking, would seem to counter the original quote nicely, in showing that the law of course prevents Rich and poor alike in doing things that they have interests in doing, but no poor person is insider trading or dumping hazardous materials from their factories, because the definition of poor includes that they cannot be doing these things.
The thing of course is that the poor may have an interest in insider trading but lack the capacity, whereas everybody has the capacity to sleep under bridges but only the poor really seem to have an interest in it, and really they only have that interest because they are poor.
Which leads me to the following conclusion:
The interests of the poor are forbidden. The capacities of the rich are regulated.
