We still need to show that $\mu_n \implies \mu$. We still need to show that $\mu_n \implies \mu$.
\begin{fact} \begin{fact}
Suppose $a_n$ is a bounded sequence in $\R$, Suppose $a_n$ is a bounded sequence in $\R$,
such that any subsequence converges to $a \in \R$. such that any subsequence has a subsequence
that converges to $a \in \R$.
Then $a_n \to a$. Then $a_n \to a$.
