Firstly, the scenario is exact in its implication. All things held equal, an "Islamic", "jihadist", "immigrant" is treated with greater caution than an "armed" "toddler". Secondly, you can not infer the population of "armed" "toddlers" or "Islamic", "jihadist", "immigrants" from this statistic. Terrorists could be incredibly common and safe or uncommon and dangerous. Increasing their commonality might not be desirable. Which directly contradicts the implication of the tweet. Thirdly, proportion the population of toddlers and terrorists however you wish. Under any proportionment the terrorist would be addressed first. For the simple fact that terrorists have intent to harm, whereas toddlers are more likely to harm themselves.
