Would one be permitted to study the Tochacha on Tish'a B'Av?
It's not about the fast and is not mentioned in the list of things one may learn on Tish'a B'Av as it doesn't pertain to the destruction per se, but it is not a happy subject matter and ultimately does predict the destruction and exile.
And, if permitted, would there be a difference between learning the Tochacha in בְּחֻקֹּתַי and כִּי-תָבוֹא?
Any sources or conjectures appreciated.
